The initialization of "security_hook_heads" is done by casting it to another structure pointer type, and treating it as an array of "struct hlist_head" objects. This requires an exception be made in "randstruct", because otherwise it will emit an error, reducing the effectiveness of the hardening technique. Instead of using a cast, initialize the individual struct hlist_head elements in security_hook_heads explicitly. This removes the need for the cast and randstruct exception.

If you have a vmalloc() allocation, or an address from calling vmap(), you cannot overrun the vm_area which describes it, regardless of the size of the underlying allocation. This probably doesn't do much for security because vmalloc comes with guard pages these days, but it prevents usercopy aborts when copying to a vmap() of smaller pages.

If you are copying to an address in the kmap region, you may not copy across a page boundary, no matter what the size of the underlying allocation. You can't kmap() a slab page because slab pages always come from low memory.

struct stat (defined in arch/x86/include/uapi/asm/stat.h) has 32-bit st_dev and st_rdev; struct compat_stat (defined in arch/x86/include/asm/compat.h) has 16-bit st_dev and st_rdev followed by a 16-bit padding. This patch fixes struct compat_stat to match struct stat. [ Historical note: the old x86 'struct stat' did have that 16-bit field that the compat layer had kept around, but it was changes back in 2003 by "struct stat - support larger dev_t": https://git.kernel.org/pub/scm/linux/kernel/git/tglx/history.git/commit/?id=e95b2065677fe32512a597a79db94b77b90c968d and back in those days, the x86_64 port was still new, and separate from the i386 code, and had already picked up the old version with a 16-bit st_dev field ] Note that we can't change compat_dev_t because it is used by compat_loop_info. Also, if the st_dev and st_rdev values are 32-bit, we don't have to use old_valid_dev to test if the value fits into them. This fixes -EOVERFLOW on filesystems that are on NVMe because NVMe uses the major number 259.

Jason A. Donenfeld authored
While the latent entropy plugin mostly doesn't derive entropy from get_random_const() for measuring the call graph, when __latent_entropy is applied to a constant, then it's initialized statically to output from get_random_const(). In that case, this data is derived from a 64-bit seed, which means a buffer of 512 bits doesn't really have that amount of compile-time entropy. This patch fixes that shortcoming by just buffering chunks of /dev/urandom output and doling it out as requested. At the same time, it's important that we don't break the use of -frandom-seed, for people who want the runtime benefits of the latent entropy plugin, while still having compile-time determinism. In that case, we detect whether gcc's set_random_seed() has been called by making a call to get_random_seed(noinit=true) in the plugin init function, which is called after set_random_seed() is called but before anything that calls get_random_seed(noinit=false), and seeing if it's zero or not. If it's not zero, we're in deterministic mode, and so we just generate numbers with a basic xorshift prng. Note that we don't detect if -frandom-seed is being used using the documented local_tick variable, because it's assigned via: local_tick = (unsigned) tv.tv_sec * 1000 + tv.tv_usec / 1000; which may well overflow and become -1 on its own, and so isn't reliable: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105171 [kees: The 256 byte rnd_buf size was chosen based on average (250), median (64), and std deviation (575) bytes of used entropy for a defconfig x86_64 build] Fixes: 38addce8 ("gcc-plugins: Add latent_entropy plugin") Cc: stable@vger.kernel.org Cc: PaX Team <pageexec@freemail.hu> Signed-off-by: Jason A.

The WARN was introduced by commit 03c0304a86bc ("KVM: Warn if mark_page_dirty() is called without an active vCPU") but the change seems to be correct (unlike Hyper-V TSC page update mechanism). In fact, there's no real need to actually write to guest memory to invalidate TSC page, this can be done by the first vCPU which goes through kvm_guest_time_update().

They are the final bits in the removal of the default_attrs field in struct kobj_type. I had to wait until after 5.18-rc1 for all of the changes to do this came in through different development trees, and then one new user snuck in. So this series has two changes: - removal of the default_attrs field in the powerpc/pseries/vas code. The change has been acked by the PPC maintainers to come through this tree - removal of default_attrs from struct kobj_type now that all in-kernel users are removed. This cleans up the kobject code a little bit and removes some duplicated functionality that confused people (now there is only one way to do default groups) Both of these have been in linux-next for all of this week with no reported problems" * tag 'driver-core-5.18-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: kobject: kobj_type: remove default_attrs powerpc/pseries/vas: use default_groups in kobj_type

The `perf --list-cmds` output prints only internal commands, although there is no reason for that from users' perspective. Adding the external commands to commands array with NULL function pointer allows printing all perf commands while not changing the logic of command handler selection.

If a perf event doesn't fit into remaining buffer space return NULL to remap buf and fetch the event again. Keep the logic to error out on inadequate input from fuzzing. This fixes perf failing on ChromeOS (with 32b userspace): $ perf report -v -i perf.data ... prefetch_event: head=0x1fffff8 event->header_size=0x30, mmap_size=0x2000000: fuzzed or compressed perf.data?

Fix firmware file names assignment in si2157 tuner, allow for running devices without firmware files needed. modprobe gives error: unknown chip version Si2147-A30 ROM 0x50 Device initialization is interrupted. Caused by: 1. table si2157_tuners has swapped fields rom_id and required vs struct si2157_tuner_info. 2. both firmware file names can be null for devices with required == false - device uses build-in firmware in this case Tested on this device: m07ca:1871 AVerMedia Technologies, Inc.

The 'perf bench epoll' testcase fails on systems with more than 1K CPUs. Testcase: perf bench epoll all Result snippet: <<>> Run summary [PID 106497]: 1399 threads monitoring on 64 file-descriptors for 8 secs. perf: pthread_create: No such file or directory <<>> In epoll benchmarks (ctl, wait) pthread_create is invoked in do_threads from respective bench_epoll_* function. Though the logs shows direct failure from pthread_create, the actual failure is from "sched_setaffinity" returning EINVAL (invalid argument). This happens because the default mask size in glibc is 1024. To overcome this 1024 CPUs mask size limitation of cpu_set_t, change the mask size using the CPU_*_S macros. Patch addresses this by fixing all the epoll benchmarks to use CPU_ALLOC to allocate cpumask, CPU_ALLOC_SIZE for size, and CPU_SET_S to set the mask.
