Pull SELinux updates from Paul Moore: "The highlights: - A number of improvements to various SELinux internal data structures to help improve performance. We move the role transitions into a hash table. In the content structure we shift from hashing the content string (aka SELinux label) to the structure itself, when it is valid. This last change not only offers a speedup, but it helps us simplify the code some as well. - Add a new SELinux policy version which allows for a more space efficient way of storing the filename transitions in the binary policy. Given the default Fedora SELinux policy with the unconfined module enabled, this change drops the policy size from ~7.6MB to ~3.3MB. The kernel policy load time dropped as well. - Some fixes to the error handling code in the policy parser to properly return error codes when things go wrong" * tag 'selinux-pr-20200601' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/selinux: selinux: netlabel: Remove unused inline function selinux: do not allocate hashtabs dynamically selinux: fix return value on error in policydb_read() selinux: simplify range_write() selinux: fix error return code in policydb_read() selinux: don't produce incorrect filename_trans_count selinux: implement new format of filename transitions selinux: move context hashing under sidtab selinux: hash context structure directly selinux: store role transitions in a hash table selinux: drop unnecessary smp_load_acquire() call selinux: fix warning Comparison to bool -

Commit 8d58f222 ("ubsan: disable UBSAN_ALIGNMENT under COMPILE_TEST") tried to fix the pathological results of UBSAN_ALIGNMENT with UBSAN_TRAP (which objtool would rightly scream about), but it made an assumption about how COMPILE_TEST gets set (it is not set for randconfig). As a result, we need a bigger hammer here: just don't allow the alignment checks with the trap mode. Fixes: 8d58f222 ("ubsan: disable UBSAN_ALIGNMENT under COMPILE_TEST") Reported-by:

KASAN uses a single cc-option invocation to disable both conserve-stack and stack-protector flags. The former flag is not present in Clang, which causes cc-option to fail, and results in stack-protector being enabled. Fix by using separate cc-option calls for each flag. Also collect all flags in a variable to avoid calling cc-option multiple times for different files. Reported-by:

Patch series "mm: Get rid of vmalloc_sync_(un)mappings()", v3. After the recent issue with vmalloc and tracing code[1] on x86 and a long history of previous issues related to the vmalloc_sync_mappings() interface, I thought the time has come to remove it. Please see [2], [3], and [4] for some other issues in the past. The patches add tracking of page-table directory changes to the vmalloc and ioremap code. Depending on which page-table levels changes have been made, a new per-arch function is called: arch_sync_kernel_mappings(). On x86-64 with 4-level paging, this function will not be called more than 64 times in a systems runtime (because vmalloc-space takes 64 PGD entries which are only populated, but never cleared). As a side effect this also allows to get rid of vmalloc faults on x86, making it safe to touch vmalloc'ed memory in the page-fault handler. Note that this potentially includes per-cpu memory. This patch (of 7): Add page-table allocation functions which will keep track of changed directory entries. They are needed for new PGD, P4D, PUD, and PMD entries and will be used in vmalloc and ioremap code to decide whether any changes in the kernel mappings need to be synchronized between page-tables in the system.

The non-cached vmalloc mapping was initially added as a hack for the first-gen amigaone platform (6xx/book32s), isn't fully supported upstream, and which used the legacy radeon driver together with non-coherent DMA. However this only ever worked reliably for DRI . Remove the hack as it is the last user of __vmalloc passing a page protection flag other than PAGE_KERNEL and didn't do anything for other platforms with non-coherent DMA. Signed-off-by:
