| * crypto: sig - Add interface for sign/verifyHerbert Xu2023-06-235-17/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split out the sign/verify functionality from the existing akcipher interface. Most algorithms in akcipher either support encryption and decryption, or signing and verify. Only one supports both. As a signature algorithm may not support encryption at all, these two should be spearated. For now sig is simply a wrapper around akcipher as all algorithms remain unchanged. This is a first step and allows users to start allocating sig instead of akcipher. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
| * crypto: akcipher - Add sync interface without SG listsHerbert Xu2023-06-231-0/+95
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The only user of akcipher does not use SG lists. Therefore forcing users to use SG lists only results unnecessary overhead. Add a new interface that supports arbitrary kernel pointers. For the time being the copy will be performed unconditionally. But this will go away once the underlying interface is updated. Note also that only encryption and decryption is addressed by this patch as sign/verify will go into a new interface (sig). Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With the update of the permanent and intermittent health errors, the actual indicator for the health test indicates a potential error only for the one offending time stamp gathered in the current iteration round. The next iteration round will "overwrite" the health test result. Thus, the entropy collection loop in jent_gen_entropy checks for the health test failure upon each loop iteration. However, the initialization operation checked for the APT health test once for an APT window which implies it would not catch most errors. Thus, the check for all health errors is now invoked unconditionally during each loop iteration for the startup test. With the change, the error JENT_ERCT becomes unused as all health errors are only reported with the JENT_HEALTH return code. This allows the removal of the error indicator.

| * crypto: jitter - add interface for gathering of raw entropyStephan Müller2023-05-125-1/+333
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The test interface allows a privileged process to capture the raw unconditioned noise that is collected by the Jitter RNG for statistical analysis. Such testing allows the analysis how much entropy the Jitter RNG noise source provides on a given platform. The obtained data is the time stamp sampled by the Jitter RNG. Considering that the Jitter RNG inserts the delta of this time stamp compared to the immediately preceding time stamp, the obtained data needs to be post-processed accordingly to obtain the data the Jitter RNG inserts into its entropy pool. The raw entropy collection is provided to obtain the raw unmodified time stamps that are about to be added to the Jitter RNG entropy pool and are credited with entropy. Thus, this patch adds an interface which renders the Jitter RNG insecure. This patch is NOT INTENDED FOR PRODUCTION SYSTEMS, but solely for development/test systems to verify the available entropy rate. Access to the data is given through the jent_raw_hires debugfs file. The data buffer should be multiples of sizeof(u32) to fill the entire buffer. Using the option jitterentropy_testing.boot_raw_hires_test=1 the raw noise of the first 1000 entropy events since boot can be sampled. This test interface allows generating the data required for analysis whether the Jitter RNG is in compliance with SP800-90B sections 3.1.3 and 3.1.4. If the test interface is not compiled, its code is a noop which has no impact on the performance.

| * crypto: jitter - replace LFSR with SHA3-256Stephan Müller2023-05-124-120/+219
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the kernel crypto API, the SHA3-256 algorithm is used as conditioning element to replace the LFSR in the Jitter RNG. All other parts of the Jitter RNG are unchanged. The application and use of the SHA-3 conditioning operation is identical to the user space Jitter RNG 3.4.0 by applying the following concept: - the Jitter RNG initializes a SHA-3 state which acts as the "entropy pool" when the Jitter RNG is allocated. - When a new time delta is obtained, it is inserted into the "entropy pool" with a SHA-3 update operation. Note, this operation in most of the cases is a simple memcpy() onto the SHA-3 stack. - To cause a true SHA-3 operation for each time delta operation, a second SHA-3 operation is performed hashing Jitter RNG status information. The final message digest is also inserted into the "entropy pool" with a SHA-3 update operation. Yet, this data is not considered to provide any entropy, but it shall stir the entropy pool. - To generate a random number, a SHA-3 final operation is performed to calculate a message digest followed by an immediate SHA-3 init to re-initialize the "entropy pool". The obtained message digest is one block of the Jitter RNG that is returned to the caller. Mathematically speaking, the random number generated by the Jitter RNG is: aux_t = SHA-3(Jitter RNG state data) Jitter RNG block = SHA-3(time_i || aux_i || time_(i-1) || aux_(i-1) || ... || time_(i-255) || aux_(i-255)) when assuming that the OSR = 1, i.e. the default value. This operation implies that the Jitter RNG has an output-blocksize of 256 bits instead of the 64 bits of the LFSR-based Jitter RNG that is replaced with this patch. The patch also replaces the varying number of invocations of the conditioning function with one fixed number of invocations. The use of the conditioning function consistent with the userspace Jitter RNG library version 3.4.0. The code is tested with a system that exhibited the least amount of entropy generated by the Jitter RNG: the SiFive Unmatched RISC-V system. The measured entropy rate is well above the heuristically implied entropy value of 1 bit of entropy per time delta. On all other tested systems, the measured entropy rate is even higher by orders of magnitude. The measurement was performed using updated tooling provided with the user space Jitter RNG library test framework. The performance of the Jitter RNG with this patch is about en par with the performance of the Jitter RNG without the patch.

Fix this by handling zero-length sends at the top of the hash_sendmsg() function. If we're not continuing the previous sendmsg(), then just ignore the send (hash_recvmsg() will invent something when called); if we are continuing, then we finalise the request at this point if MSG_MORE is not set to get any error here, otherwise the send is of no effect and can be ignored. Whilst we're at it, remove the code to create a kvmalloc'd scatterlist if we get more than ALG_MAX_PAGES - this shouldn't happen.

However, more recently commit ba14a194a434c ("fork: Add generic vmalloced stack support") made it possible to move the stack in the vmalloc area, which is not contiguous, and thus not suitable for sg_set_buf() which needs adjacent pages. Always make a copy of the signature and digest in the same buffer used to store the key and its parameters, and pass them to sg_init_one(). Prefer it to conditionally doing the copy if necessary, to keep the code simple. The buffer allocated with kmalloc() is in the linear mapping area.

At that point, crypto_engine backlogs the request and returns -EBUSY. Calling driver such as dm-crypt then waits until the complete() function is called with a status of -EINPROGRESS before sending a new request. The problem lies in the call to complete() with a value of -EINPROGRESS that is made when a backlog item is present on the queue. The call is done before the successful execution of the crypto request. In the case that do_one_request() returns < 0 and the retry support is available, the request is put back in the queue. This leads upper drivers to send a new request even if the queue is still full. The problem can be reproduced by doing a large dd into a crypto dm-crypt device. This is pretty easy to see when using Freescale CAAM crypto driver and SWIOTLB dma. Since the actual amount of requests that can be hold in the queue is unlimited we get IOs error and dma allocation. The fix is to call complete with a value of -EINPROGRESS only if the request is not enqueued back in crypto_queue. This is done by calling complete() later in the code. In order to delay the decision, crypto_queue is modified to correctly set the backlog pointer when a request is enqueued back.

Most of the changes have been in linux-next for quite some time except the minor fixes I made to check if a module was already loaded prior to allocating the final module memory with vmalloc and the respective debug code it introduces to help clarify the issue. Although the functional change is small it is rather safe as it can only *help* reduce vmalloc space for duplicates and is confirmed to fix a bootup issue with over 400 CPUs with KASAN enabled. I don't expect stable kernels to pick up that fix as the cleanups would have also had to have been picked up. Folks on larger CPU systems with modules will want to just upgrade if vmalloc space has been an issue on bootup. Given the size of this request, here's some more elaborate details: The functional change change in this pull request is the very first patch from Song Liu which replaces the 'struct module_layout' with a new 'struct module_memory'. The old data structure tried to put together all types of supported module memory types in one data structure, the new one abstracts the differences in memory types in a module to allow each one to provide their own set of details. This paves the way in the future so we can deal with them in a cleaner way. If you look at changes they also provide a nice cleanup of how we handle these different memory areas in a module. This change has been in linux-next since before the merge window opened for v6.3 so to provide more than a full kernel cycle of testing. It's a good thing as quite a bit of fixes have been found for it. Jason Baron then made dynamic debug a first class citizen module user by using module notifier callbacks to allocate / remove module specific dynamic debug information. Nick Alcock has done quite a bit of work cross-tree to remove module license tags from things which cannot possibly be module at my request so to: a) help him with his longer term tooling goals which require a deterministic evaluation if a piece a symbol code could ever be part of a module or not. But quite recently it is has been made clear that tooling is not the only one that would benefit. Disambiguating symbols also helps efforts such as live patching, kprobes and BPF, but for other reasons and R&D on this area is active with no clear solution in sight. b) help us inch closer to the now generally accepted long term goal of automating all the MODULE_LICENSE() tags from SPDX license tags In so far as a) is concerned, although module license tags are a no-op for non-modules, tools which would want create a mapping of possible modules can only rely on the module license tag after the commit 8b41fc4454e ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"). Nick has been working on this *for years* and AFAICT I was the only one to suggest two alternatives to this approach for tooling. The complexity in one of my suggested approaches lies in that we'd need a possible-obj-m and a could-be-module which would check if the object being built is part of any kconfig build which could ever lead to it being part of a module, and if so define a new define -DPOSSIBLE_MODULE [0]. A more obvious yet theoretical approach I've suggested would be to have a tristate in kconfig imply the same new -DPOSSIBLE_MODULE as well but that means getting kconfig symbol names mapping to modules always, and I don't think that's the case today. I am not aware of Nick or anyone exploring either of these options. Quite recently Josh Poimboeuf has pointed out that live patching, kprobes and BPF would benefit from resolving some part of the disambiguation as well but for other reasons. The function granularity KASLR (fgkaslr) patches were mentioned but Joe Lawrence has clarified this effort has been dropped with no clear solution in sight [1]. In the meantime removing module license tags from code which could never be modules is welcomed for both objectives mentioned above. Some developers have also welcomed these changes as it has helped clarify when a module was never possible and they forgot to clean this up, and so you'll see quite a bit of Nick's patches in other pull requests for this merge window. I just picked up the stragglers after rc3. LWN has good coverage on the motivation behind this work [2] and the typical cross-tree issues he ran into along the way. The only concrete blocker issue he ran into was that we should not remove the MODULE_LICENSE() tags from files which have no SPDX tags yet, even if they can never be modules. Nick ended up giving up on his efforts due to having to do this vetting and backlash he ran into from folks who really did *not understand* the core of the issue nor were providing any alternative / guidance. I've gone through his changes and dropped the patches which dropped the module license tags where an SPDX license tag was missing, it only consisted of 11 drivers. To see if a pull request deals with a file which lacks SPDX tags you can just use: ./scripts/spdxcheck.py -f \ $(git diff --name-only commid-id | xargs echo) You'll see a core module file in this pull request for the above, but that's not related to his changes. WE just need to add the SPDX license tag for the kernel/module/kmod.c file in the future but it demonstrates the effectiveness of the script. Most of Nick's changes were spread out through different trees, and I just picked up the slack after rc3 for the last kernel was out. Those changes have been in linux-next for over two weeks. The cleanups, debug code I added and final fix I added for modules were motivated by David Hildenbrand's report of boot failing on a systems with over 400 CPUs when KASAN was enabled due to running out of virtual memory space. Although the functional change only consists of 3 lines in the patch "module: avoid allocation if module is already present and ready", proving that this was the best we can do on the modules side took quite a bit of effort and new debug code. The initial cleanups I did on the modules side of things has been in linux-next since around rc3 of the last kernel, the actual final fix for and debug code however have only been in linux-next for about a week or so but I think it is worth getting that code in for this merge window as it does help fix / prove / evaluate the issues reported with larger number of CPUs. Userspace is not yet fixed as it is taking a bit of time for folks to understand the crux of the issue and find a proper resolution. Worst come to worst, I have a kludge-of-concept [3] of how to make kernel_read*() calls for modules unique / converge them, but I'm currently inclined to just see if userspace can fix this instead" Link: https://lore.kernel.org/all/Y/kXDqW+7d71C4wz@bombadil.infradead.org/ [0] Link: https://lkml.kernel.org/r/025f2151-ce7c-5630-9b90-98742c97ac65@redhat.com [1] Link: https://lwn.net/Articles/927569/ [2] Link: https://lkml.kernel.org/r/20230414052840.1994456-3-mcgrof@kernel.org [3] * tag 'modules-6.4-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/mcgrof/linux: (121 commits) module: add debugging auto-load duplicate module support module: stats: fix invalid_mod_bytes typo module: remove use of uninitialized variable len module: fix building stats for 32-bit targets module: stats: include uapi/linux/module.h module: avoid allocation if module is already present and ready module: add debug stats to help identify memory pressure module: extract patient module check into helper modules/kmod: replace implementation with a semaphore Change DEFINE_SEMAPHORE() to take a number argument module: fix kmemleak annotations for non init ELF sections module: Ignore L0 and rename is_arm_mapping_symbol() module: Move is_arm_mapping_symbol() to module_symbol.h module: Sync code of is_arm_mapping_symbol() scripts/gdb: use mem instead of core_layout to get the module address interconnect: remove module-related code interconnect: remove MODULE_LICENSE in non-modules zswap: remove MODULE_LICENSE in non-modules zpool: remove MODULE_LICENSE in non-modules x86/mm/dump_pagetables: remove MODULE_LICENSE in non-modules ...

So remove it in the files in this commit, none of which can be built as modules.

The document also shows vectors for camellia-cmac-96, and for VK with a length greater than 16, but I'm not sure how to express those in testmgr. This also leaves cts(cbc(camellia)) untested, but I can't seem to find any tests for that that I could put into testmgr.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cryptd hash template was still using the obsolete cra_init/cra_exit interface. Make it use the modern ahash init_tfm/exit_tfm instead.
