| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When more than 255 elements expired we're supposed to switch to a new gc container structure. This never happens: u8 type will wrap before reaching the boundary and nft_trans_gc_space() always returns true. This means we recycle the initial gc container structure and lose track of the elements that came before. While at it, don't deref 'gc' after we've passed it to call_rcu.

Add __LINE__ number suffix to make BTF_ID symbol more unique, which is not a complete fix, but it would help for now and meanwhile we can work on better solution as suggested by Andrii.

This is in the conflict with its UAPI doc which says the following: "0 on success, or a negative error in case of failure." Update the UAPI to reflect the fact that bpf_clone_redirect can return positive error numbers, but don't explicitly define their meaning.

This rule deletion support does not make sense and userspace does not use this. Problem exists since the introduction of chain binding support. 2) rbtree GC worker only collects the elements that have expired. This operation is not destructive, therefore, turn write into read spinlock to avoid datapath contention due to GC worker run. This was not fixed in the recent GC fix batch in the 6.5 cycle. 3) pipapo set backend performs sync GC, therefore, catchall elements must use sync GC queue variant. This bug was introduced in the 6.5 cycle with the recent GC fixes. 4) Stop GC run if memory allocation fails in pipapo set backend, otherwise access to NULL pointer to GC transaction object might occur. This bug was introduced in the 6.5 cycle with the recent GC fixes. 5) rhash GC run uses an iterator that might hit EAGAIN to rewind, triggering double-collection of the same element. This bug was introduced in the 6.5 cycle with the recent GC fixes. 6) Do not permit to remove elements in anonymous sets, this type of sets are populated once and then bound to rules. This fix is similar to the chain binding patch coming first in this batch. API permits since the very beginning but it has no use case from userspace. ==================== Signed-off-by: David S.

While we were polishing those up after Linus realized that there might be a nicer way to fix them we received a regression report in [2] that fine grained timestamps break gnulib tests and thus possibly other tools. The kernel will elide fine-grain timestamp updates when no one is actively querying for them to avoid performance impacts. So a sequence like write(f1) stat(f2) write(f2) stat(f2) write(f1) stat(f1) may result in timestamp f1 to be older than the final f2 timestamp even though f1 was last written too but the second write didn't update the timestamp. Such plotholes can lead to subtle bugs when programs compare timestamps. For example, the nap() function in [2] will estimate that it needs to wait one ns on a fine-grain timestamp enabled filesytem between subsequent calls to observe a timestamp change. But in general we don't update timestamps with more than one jiffie if we think that no one is actively querying for fine-grain timestamps to avoid performance impacts. While discussing various fixes the decision was to go back to the drawing board and ultimately to explore a solution that involves only exposing such fine-grained timestamps to nfs internally and never to userspace. As there are multiple solutions discussed the honest thing to do here is not to fix this up or disable it but to cleanly revert. The general infrastructure will probably come back but there is no reason to keep this code in mainline. The general changes to timestamp handling are valid and a good cleanup that will stay.

Other IPs would be added as they fall under the pnfs trunking rules. For the list of IPs the 1st goes thru calling nfs4_set_ds_client() which will eventually call nfs4_add_trunk() and call into rpc_clnt_test_and_add_xprt() which has the check for MDS trunking. The other IPs (after the 1st one), would call rpc_clnt_add_xprt() which doesn't go thru that check. nfs4_add_trunk() is called when MDS trunking is happening and it needs to enforce the usage of max_connect mount option of the 1st mount. However, this shouldn't be applied to pnfs flow. Instead, this patch proposed to treat MDS=DS as DS trunking and make sure that MDS's max_connect limit does not apply to the 1st IP returned in the GETDEVICEINFO list. It does so by marking the newly created client with a new flag NFS_CS_PNFS which then used to pass max_connect value to use into the rpc_clnt_test_and_add_xprt() instead of the existing rpc client's max_connect value set by the MDS connection. For example, mount was done without max_connect value set so MDS's rpc client has cl_max_connect=1. Upon calling into rpc_clnt_test_and_add_xprt() and using rpc client's value, the caller passes in max_connect value which is previously been set in the pnfs path (as a part of handling GETDEVICEINFO list of IPs) in nfs4_set_ds_client(). However, when NFS_CS_PNFS flag is not set and we know we are doing MDS trunking, comparing a new IP of the same server, we then set the max_connect value to the existing MDS's value and pass that into rpc_clnt_test_and_add_xprt().

In AHCI 1.3.1, the register description for CAP.PSC: "When cleared to ‘0’, software must not allow the HBA to initiate transitions to the Partial state via agressive link power management nor the PxCMD.ICC field in each port, and the PxSCTL.IPM field in each port must be programmed to disallow device initiated Partial requests." Ensure that we always set the corresponding bits in PxSCTL.IPM, such that a device is not allowed to initiate transitions to power states which are unsupported by the HBA. DevSleep is always initiated by the HBA, however, for completeness, set the corresponding bit in PxSCTL.IPM such that agressive link power management cannot transition to DevSleep if DevSleep is not supported. sata_link_scr_lpm() is used by libahci, ata_piix and libata-pmp. However, only libahci has the ability to read the CAP/CAP2 register to see if these features are supported. Therefore, in order to not introduce any regressions on ata_piix or libata-pmp, create flags that indicate that the respective feature is NOT supported. This way, the behavior for ata_piix and libata-pmp should remain unchanged. This change is based on a patch originally submitted by Runa Guo-oc.

Fix this by simply make the driver device-managed as well. In short, the sequence leading to the UAF is as follows: INIT: Code allocates a struct device as a kunit-managed resource. Code allocates a drm driver as a kunit-managed resource. Code allocates a drm device as a device-managed resource. EXIT: Kunit resource cleanup frees the drm driver Kunit resource cleanup puts the struct device, which starts a device-managed resource cleanup device-managed cleanup calls drm_dev_put() drm_dev_put() dereferences the (now freed) drm driver -> Boom.

Also the lock allocation tracking code will apparently register only the address of the first mutex of a given class locked in a sequence. This has the odd consequence that if that first mutex is unlocked while other mutexes of the same class remain locked and then its memory then freed, the lock alloc tracking code will incorrectly assume that memory is freed with a held lock in there. For now, work around that for drm_exec by releasing the first grabbed object lock last. v2: - Fix a typo (Danilo Krummrich) - Reword the commit message a bit. - Add a Fixes: tag Related lock alloc tracking warning: [ 322.660067] ========================= [ 322.660070] WARNING: held lock freed!

If we bind() a TCPv6 socket to ::FFFF:0.0.0.0 and then bind() a TCPv4 socket to 127.0.0.1, the 2nd bind() should fail but now succeeds. from socket import * s1 = socket(AF_INET6, SOCK_STREAM) s1.bind(('::ffff:0.0.0.0', 0)) s2 = socket(AF_INET, SOCK_STREAM) s2.bind(('127.0.0.1', s1.getsockname()[1])) During the 2nd bind(), if tb->family is AF_INET6 and sk->sk_family is AF_INET in inet_bind2_bucket_match_addr_any(), we still need to check if tb has the v4-mapped-v6 wildcard address. The example above does not work after commit 5456262d2baa ("net: Fix incorrect address comparison when searching for a bind2 bucket"), but the blamed change is not the commit. Before the commit, the leading zeros of ::FFFF:0.0.0.0 were treated as 0.0.0.0, and the sequence above worked by chance. Technically, this case has been broken since bhash2 was introduced. Note that if we bind() two sockets to 127.0.0.1 and then ::FFFF:0.0.0.0, the 2nd bind() fails properly because we fall back to using bhash to detect conflicts for the v4-mapped-v6 address.

That is, If a event file is opened for an instance, there's nothing preventing the instance from being removed which will make accessing the files cause use-after-free bugs. - Fix a ring buffer race that happens when iterating over the ring buffer while writers are active. Check to make sure not to read the event meta data if it's beyond the end of the ring buffer sub buffer. - Fix the print trigger that disappeared because the test to create it was looking for the event dir field being filled, but now it has the "ef" field filled for the eventfs structure. - Remove the unused "dir" field from the event structure. - Fix the order of the trace_dynamic_info as it had it backwards for the offset and len fields for which one was for which endianess. - Fix NULL pointer dereference with eventfs_remove_rec() If an allocation fails in one of the eventfs_add_*() functions, the caller of it in event_subsystem_dir() or event_create_dir() assigns the result to the structure. But it's assigning the ERR_PTR and not NULL. This was passed to eventfs_remove_rec() which expects either a good pointer or a NULL, not ERR_PTR. The fix is to not assign the ERR_PTR to the structure, but to keep it NULL on error. - Fix list_for_each_rcu() to use list_for_each_srcu() in dcache_dir_open_wrapper(). One iteration of the code used RCU but because it had to call sleepable code, it had to be changed to use SRCU, but one of the iterations was missed. - Fix synthetic event print function to use "as_u64" instead of passing in a pointer to the union. To fix big/little endian issues, the u64 that represented several types was turned into a union to define the types properly. * tag 'trace-v6.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: eventfs: Fix the NULL pointer dereference bug in eventfs_remove_rec() tracefs/eventfs: Use list_for_each_srcu() in dcache_dir_open_wrapper() tracing/synthetic: Print out u64 values properly tracing/synthetic: Fix order of struct trace_dynamic_info selftests/ftrace: Fix dependencies for some of the synthetic event tests tracing: Remove unused trace_event_file dir field tracing: Use the new eventfs descriptor for print trigger ring-buffer: Do not attempt to read past "commit" tracefs/eventfs: Free top level files on removal ring-buffer: Avoid softlockup in ring_buffer_resize() tracing: Have event inject files inc the trace array ref count tracing: Have option files inc the trace array ref count tracing: Have current_trace inc the trace array ref count tracing: Have tracing_max_latency inc the trace array ref count tracing: Increase trace array ref count on enable and filter files tracefs/eventfs: Use dput to free the toplevel events directory tracefs/eventfs: Add missing lockdown checks tracefs: Add missing lockdown check to tracefs_create_dir()
