| | | | | | | | | | | | | | | | | | | | Commit e2be04c7f995 ("License cleanup: add SPDX license identifier to uapi header files with a license") added the correct SPDX identifier to include/uapi/linux/netfilter/xt_IDLETIMER.h. A subsequent commit removed it for no reason and reintroduced the UAPI license incorrectness as the file is now missing the UAPI exception again. Add it back and remove the GPLv2 boilerplate while at it.

While it's not freed back to system correctly when kdump kernel is reloaded or unloaded. Then memory leak is caused. Fix it by introducing x86 specific function arch_kimage_file_post_load_cleanup(), and freeing the buffer there. And also remove the incorrect elf header buffer freeing code. Before calling arch specific kexec_file loading function, the image instance has been initialized. So 'image->elf_headers' must be NULL. It doesn't make sense to free the elf header buffer in the place. Three different people have reported three bugs about the memory leak on x86_64 inside Redhat.

* | | bluetooth: don't use bitmaps for random flag accessesLinus Torvalds2022-06-055-39/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bluetooth code uses our bitmap infrastructure for the two bits (!) of connection setup flags, and in the process causes odd problems when it converts between a bitmap and just the regular values of said bits. It's completely pointless to do things like bitmap_to_arr32() to convert a bitmap into a u32. It shoudln't have been a bitmap in the first place. The reason to use bitmaps is if you have arbitrary number of bits you want to manage (not two!), or if you rely on the atomicity guarantees of the bitmap setting and clearing. The code could use an "atomic_t" and use "atomic_or/andnot()" to set and clear the bit values, but considering that it then copies the bitmaps around with "bitmap_to_arr32()" and friends, there clearly cannot be a lot of atomicity requirements. So just use a regular integer. In the process, this avoids the warnings about erroneous use of bitmap_from_u64() which were triggered on 32-bit architectures when conversion from a u64 would access two words (and, surprise, surprise, only one word is needed - and indeed overkill - for a 2-bit bitmap). That was always problematic, but the compiler seems to notice it and warn about the invalid pattern only after commit 0a97953fd221 ("lib: add bitmap_{from,to}_arr64") changed the exact implementation details of 'bitmap_from_u64()', as reported by Sudip Mukherjee and Stephen Rothwell.

These backing pages are allocated via a per-enclave shared memory area. Since SGX allows unlimited over commit on EPC memory, the reclaimer thread can allocate a large number of backing RAM pages in response to EPC memory pressure. When the shared memory backing RAM allocation occurs during the reclaimer thread context, the shared memory is charged to the root memory control group, and the shmem usage of the enclave is not properly accounted for, making cgroups ineffective at limiting the amount of RAM an enclave can consume. For example, when using a cgroup to launch a set of test enclaves, the kernel does not properly account for 50% - 75% of shmem page allocations on average. In the worst case, when nearly all allocations occur during the reclaimer thread, the kernel accounts less than a percent of the amount of shmem used by the enclave's cgroup to the correct cgroup. SGX stores a list of mm_structs that are associated with an enclave. Pick one of them during reclaim and charge that mm's memcg with the shmem allocation. The one that gets picked is arbitrary, but this list almost always only has one mm. The cases where there is more than one mm with different memcg's are not worth considering. Create a new function - sgx_encl_alloc_backing(). This function is used whenever a new backing storage page needs to be allocated. Previously the same function was used for page allocation as well as retrieving a previously allocated page. Prior to backing page allocation, if there is a mm_struct associated with the enclave that is requesting the allocation, it is set as the active memory control group.
