2019-09-12vfs: Convert ramfs, shmem, tmpfs, devtmpfs, rootfs to use the new mount APIDavid Howells6-139/+180
Convert the ramfs, shmem, tmpfs, devtmpfs and rootfs filesystems to the new internal mount API as the old one will be obsoleted and removed. This allows greater flexibility in communication of mount parameters between userspace, the VFS and the filesystem. See Documentation/filesystems/mount_api.txt for more information. Note that tmpfs is slightly tricky as it can contain embedded commas, so it can't be trivially split up using strsep() to break on commas in generic_parse_monolithic(). Instead, tmpfs has to supply its own generic parser. However, if tmpfs changes, then devtmpfs and rootfs, which are wrappers around tmpfs or ramfs, must change too - and thus so must ramfs, so these had to be converted also.

2019-09-12shmem_parse_one(): switch to use of fs_parse()Al Viro1-67/+116
This thing will eventually become our ->parse_param(), while shmem_parse_options() - ->parse_monolithic(). At that point shmem_parse_options() will start calling vfs_parse_fs_string(), rather than calling shmem_parse_one() directly. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>

2019-09-12shmem_parse_options(): don't bother with mpol in separate variableAl Viro1-6/+5
just use ctx->mpol (note that callers always set ctx->mpol to NULL when calling that). Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
2019-09-12shmem_parse_options(): use a separate structure to keep the resultsAl Viro1-43/+67
... and copy the data from it into sbinfo in the callers. For use by remount we need to keep track whether there'd been options setting max_inodes, max_blocks and huge resp. and do the sanity checks (and copying) only if such options had been seen. uid/gid/mode is ignored by remount and NULL mpol is already explicitly treated as "ignore it", so we don't need to keep track of those. Note: theoretically, mpol_parse_string() may return NULL not in case of error (for default policy), so the assumption that NULL mpol means "change nothing" is incorrect. However, that's the mainline behaviour and any changes belong in a separate patch. If we go for that, we'll need to keep track of having encountered mpol= option too.

2019-09-05devtmpfs: don't mix {ramfs,shmem}_fill_super() with mount_single()Al Viro1-6/+30
Create an internal-only type matching the current devtmpfs, never register it and have one kernel-internal mount done. That thing gets mounted only once, so it is free to use mount_nodev(). The "public" devtmpfs (the one we do register, and only after the internal mount of the real thing is done) simply gets and returns an extra reference to the internal superblock.

2019-08-16arm64: ftrace: Ensure module ftrace trampoline is coherent with I-sideWill Deacon1-9/+13
The initial support for dynamic ftrace trampolines in modules made use of an indirect branch which loaded its target from the beginning of a special section (e71a4e1bebaf7 ("arm64: ftrace: add support for far branches to dynamic ftrace")). Since no instructions were being patched, no cache maintenance was needed. However, later in be0f272bfc83 ("arm64: ftrace: emit ftrace-mod.o contents through code") this code was reworked to output the trampoline instructions directly into the PLT entry but, unfortunately, the necessary cache maintenance was overlooked. Add a call to __flush_icache_range() after writing the new trampoline instructions but before patching in the branch to the trampoline.

2019-08-16x86/boot: Save fields explicitly, zero out everything elseJohn Hubbard1-15/+48
Recent gcc compilers (gcc 9.1) generate warnings about an out of bounds memset, if the memset goes accross several fields of a struct. This generated a couple of warnings on x86_64 builds in sanitize_boot_params(). Fix this by explicitly saving the fields in struct boot_params that are intended to be preserved, and zeroing all the rest. [ tglx: Tagged for stable as it breaks the warning free build there as well ] Suggested-by: Thomas Gleixner <tglx@linutronix.de> Suggested-by: H.

2019-08-15ALSA: usb-audio: Fix a stack buffer overflow bug in check_input_termHui Peng1-8/+27
`check_input_term` recursively calls itself with input from device side (e.g., uac_input_terminal_descriptor.bCSourceID) as argument (id). In `check_input_term`, if `check_input_term` is called with the same `id` argument as the caller, it triggers endless recursive call, resulting kernel space stack overflow. This patch fixes the bug by adding a bitmap to `struct mixer_build` to keep track of the checked ids and stop the execution if some id has been checked (similar to how parse_audio_unit handles unitid argument).
