Add an extra validation of the len parameter, as for ext4 some files might have smaller file size limits than others. This also means the redundant size check in ext4_ioctl_get_es_cache can go away, as all size checking is done in the shared fiemap handler.

ext4 supports max number of logical blocks in a file to be 0xffffffff. (This is since ext4_extent's ee_block is __le32). This means that EXT4_MAX_LOGICAL_BLOCK should be 0xfffffffe (starting from 0 logical offset). This patch fixes this. The issue was seen when ext4 moved to iomap_fiemap API and when overlayfs was mounted on top of ext4. Since overlayfs was missing filemap_check_ranges(), so it could pass a arbitrary huge length which lead to overflow of map.m_len logic. This patch fixes that.

Currently, system fails to boot because the legacy interrupt remapping mode does not enable 128-bit IRTE (GA), which is required for x2APIC support. Fix by using AMD_IOMMU_GUEST_IR_LEGACY_GA mode when booting with kernel option amd_iommu_intr=legacy instead. The initialization logic will check GASup and automatically fallback to using AMD_IOMMU_GUEST_IR_LEGACY if GA mode is not supported.

While working on to make io_uring sqpoll mode support syscalls that need struct files_struct, I got cpu soft lockup in io_ring_ctx_wait_and_kill(), while (ctx->sqo_thread && !wq_has_sleeper(&ctx->sqo_wait)) cpu_relax(); above loop never has an chance to exit, it's because preempt isn't enabled in the kernel, and the context calling io_ring_ctx_wait_and_kill() and io_sq_thread() run in the same cpu, if io_sq_thread calls a cond_resched() yield cpu and another context enters above loop, then io_sq_thread() will always in runqueue and never exit. Use cond_resched() can fix this issue.

Currently checks library dependencies. - Checks if Kselftests can be built/cross-built on a system running compile test on a trivial C file with LDLIBS specified for each individual test in their Makefiles. - Prints suggested target list for a system filtering out tests failed the build dependency check from the TARGETS in Selftests the main Makefile when optional -p is specified. - Prints pass/fail dependency check for each tests/sub-test. - Prints pass/fail targets and libraries. - Default: runs dependency checks on all tests. - Optional test name can be specified to check dependencies for it. * tag 'linux-kselftest-5.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux-kselftest: selftests/ftrace: Check the first record for kprobe_args_type.tc selftests: add build/cross-build dependency check script selftests/ftrace: Check required filter files before running test

Fix the SELinux netlink_send hook to properly handle multiple netlink messages in a single sk_buff; each message is parsed and subject to SELinux access control. Prior to this patch, SELinux only inspected the first message in the sk_buff.

The struct nfs_server gets put on the cl_superblocks list before the server->super field has been initialised, in which case the call to nfs_sb_active() will Oops. Add a check to ensure that we skip such a list entry. Fixes: 3c9e502b ("NFS: Add a helper nfs_client_for_each_server()") Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
