2019-08-19media: videodev2.h: add V4L2_FMT_FLAG_DYN_RESOLUTIONMaxime Jourdan
Add an enum_fmt format flag to specifically tag coded formats where dynamic resolution switching is supported by the device. This is useful for some codec drivers that can support dynamic resolution switching for one or more of their listed coded formats. It allows userspace to know whether it should extract the video parameters itself, or if it can rely on the device to send V4L2_EVENT_SOURCE_CHANGE when such changes are detected.

2019-08-19media: videodev2.h: add V4L2_FMT_FLAG_CONTINUOUS_BYTESTREAMHans Verkuil
Add an enum_fmt format flag to specifically tag coded formats where full bytestream parsing is supported by the device. Some stateful decoders are capable of fully parsing a bytestream, but others require that userspace pre-parses the bytestream into frames or fields (see the corresponding pixelformat descriptions for details). If this flag is set, then this pre-parsing step is not required (but still possible, of course).

To fix this, "struct sockaddr_storage" needs to be aligned to 4-byte as it is only used in those packed sctp structure which is part of UAPI, and "struct __kernel_sockaddr_storage" is used in some other places of UAPI that need not to change alignments in order to not breaking userspace. Use an implicit alignment for "struct __kernel_sockaddr_storage" so it can keep the same alignments as a member in both packed and un-packed structures without breaking UAPI.

2019-07-25treewide: add "WITH Linux-syscall-note" to SPDX tag of uapi headersMasahiro Yamada
UAPI headers licensed under GPL are supposed to have exception "WITH Linux-syscall-note" so that they can be included into non-GPL user space application code. The exception note is missing in some UAPI headers. Some of them slipped in by the treewide conversion commit b24413180f56 ("License cleanup: add SPDX GPL-2.0 license identifier to files with no license"). Just run: $ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/ I believe they are not intentional, and should be fixed too. This patch was generated by the following script: git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \ -- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild | while read file do sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \ -e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file done After this patch is applied, there are 5 UAPI headers that do not contain "WITH Linux-syscall-note".

When CONFIG_UAPI_HEADER_TEST=y, exported headers are compile-tested to make sure they can be included from user-space. Currently, header.h and fw.h are excluded from the test coverage.

2019-07-16ptrace: add PTRACE_GET_SYSCALL_INFO requestElvira Khabirova
PTRACE_GET_SYSCALL_INFO is a generic ptrace API that lets ptracer obtain details of the syscall the tracee is blocked in. There are two reasons for a special syscall-related ptrace request. Firstly, with the current ptrace API there are cases when ptracer cannot retrieve necessary information about syscalls. Some examples include: * The notorious int-0x80-from-64-bit-task issue. See [1] for details. In short, if a 64-bit task performs a syscall through int 0x80, its tracer has no reliable means to find out that the syscall was, in fact, a compat syscall, and misidentifies it. * Syscall-enter-stop and syscall-exit-stop look the same for the tracer. Common practice is to keep track of the sequence of ptrace-stops in order not to mix the two syscall-stops up. But it is not as simple as it looks; for example, strace had a (just recently fixed) long-standing bug where attaching strace to a tracee that is performing the execve system call led to the tracer identifying the following syscall-exit-stop as syscall-enter-stop, which messed up all the state tracking. * Since the introduction of commit 84d77d3f06e7 ("ptrace: Don't allow accessing an undumpable mm"), both PTRACE_PEEKDATA and process_vm_readv become unavailable when the process dumpable flag is cleared. On such architectures as ia64 this results in all syscall arguments being unavailable for the tracer. Secondly, ptracers also have to support a lot of arch-specific code for obtaining information about the tracee. For some architectures, this requires a ptrace(PTRACE_PEEKUSER, ...) invocation for every syscall argument and return value. ptrace(2) man page: long ptrace(enum __ptrace_request request, pid_t pid, void *addr, void *data); ... PTRACE_GET_SYSCALL_INFO Retrieve information about the syscall that caused the stop. The information is placed into the buffer pointed by "data" argument, which should be a pointer to a buffer of type "struct ptrace_syscall_info". The "addr" argument contains the size of the buffer pointed to by "data" argument (i.e., sizeof(struct ptrace_syscall_info)). The return value contains the number of bytes available to be written by the kernel. If the size of data to be written by the kernel exceeds the size specified by "addr" argument, the output is truncated.

2019-07-16coda: add hinting support for partial file cachingPedro Cuadra
This adds support for partial file caching in Coda. Every read, write and mmap informs the userspace cache manager about what part of a file is about to be accessed so that the cache manager can ensure the relevant parts are available before the operation is allowed to proceed. When a read or write operation completes, this is also reported to allow the cache manager to track when partially cached content can be released. If the cache manager does not support partial file caching, or when the entire file has been fetched into the local cache, the cache manager may return an EOPNOTSUPP error to indicate that intent upcalls are no longer necessary until the file is closed.

2019-07-16coda: stop using 'struct timespec' in user APIArnd Bergmann
We exchange file timestamps with user space using psdev device read/write operations with a fixed but architecture specific binary layout. On 32-bit systems, this uses a 'timespec' structure that is defined by the C library to contain two 32-bit values for seconds and nanoseconds. As we get ready for the year 2038 overflow of the 32-bit signed seconds, the kernel now uses 64-bit timestamps internally, and user space will do the same change by changing the 'timespec' definition in the future. Unfortunately, this breaks the layout of the coda_vattr structure, so we need to redefine that in terms of something that does not change. I'm introducing a new 'struct vtimespec' structure here that keeps the existing layout, and the same change has to be done in the coda user space copy of linux/coda.h before anyone can use that on a 32-bit architecture with 64-bit time_t. An open question is what should happen to actual times past y2038, as they are now truncated to the last valid date when sent to user space, and interpreted as pre-1970 times when a timestamp with the MSB set is read back into the kernel. Alternatively, we could change the new timespec64_to_coda()/coda_to_timespec64() functions to use a different interpretation and extend the available range further to the future by disallowing past timestamps. This would require more changes in the user space side though.

2019-07-16uapi linux/coda.h: use __kernel_pid_t for userspaceMikko Rapeli
Part of a patch by Mikko Rapeli, as Arnd Bergman commented on the original patch. pid_t might differ between libc and the kernel, so the kernel interface has to use types that the kernel defines.

git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull pidfd and clone3 fixes from Christian Brauner: "This contains a bugfix for CLONE_PIDFD when used with the legacy clone syscall, two fixes to ensure that syscall numbering and clone3 entrypoint implementations will stay consistent, and an update for the maintainers file: - The addition of clone3 broke CLONE_PIDFD for legacy clone on all architectures that use do_fork() directly instead of calling the clone syscall itself. (Fwiw, cleaning do_fork() up is on my todo.) The reason this happened was that during conversion of _do_fork() to use struct kernel_clone_args we missed that do_fork() is called directly by various architectures. This is fixed by making sure that the pidfd argument in struct kernel_clone_args is correctly initialized with the parent_tidptr argument passed down from do_fork(). Additionally, do_fork() missed a check to make CLONE_PIDFD and CLONE_PARENT_SETTID mutually exclusive just a clone() does. This is now fixed too. - When clone3() was introduced we skipped architectures that require special handling for fork-like syscalls. Their syscall tables did not contain any mention of clone3(). To make sure that Arnd's work to make syscall numbers on all architectures identical (minus alpha) was not for naught we are placing a comment in all syscall tables that do not yet implement clone3(). The comment makes it clear that 435 is reserved for clone3 and should not be used. - Also, this contains a patch to make the clone3() syscall definition in asm-generic/unist.h conditional on __ARCH_WANT_SYS_CLONE3. This lets us catch new architectures that implicitly make use of clone3 without setting __ARCH_WANT_SYS_CLONE3 which is a good indicator that they did not check whether it needs special treatment or not. - Finally, this contains a patch to add me as maintainer for pidfd stuff so people can start blaming me (more)" * tag 'for-linus-20190715' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: MAINTAINERS: add new entry for pidfd api unistd: protect clone3 via __ARCH_WANT_SYS_CLONE3 arch: mark syscall number 435 reserved for clone3 clone: fix CLONE_PIDFD support
