2019-07-10Merge tag 'pidfd-updates-v5.3' of ↵Linus Torvalds1-0/+1
git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull pidfd updates from Christian Brauner: "This adds two main features. - First, it adds polling support for pidfds. This allows process managers to know when a (non-parent) process dies in a race-free way. The notification mechanism used follows the same logic that is currently used when the parent of a task is notified of a child's death. With this patchset it is possible to put pidfds in an {e}poll loop and get reliable notifications for process (i.e. thread-group) exit. - The second feature compliments the first one by making it possible to retrieve pollable pidfds for processes that were not created using CLONE_PIDFD. A lot of processes get created with traditional PID-based calls such as fork() or clone() (without CLONE_PIDFD). For these processes a caller can currently not create a pollable pidfd. This is a problem for Android's low memory killer (LMK) and service managers such as systemd. Both patchsets are accompanied by selftests. It's perhaps worth noting that the work done so far and the work done in this branch for pidfd_open() and polling support do already see some adoption: - Android is in the process of backporting this work to all their LTS kernels [1] - Service managers make use of pidfd_send_signal but will need to wait until we enable waiting on pidfds for full adoption. - And projects I maintain make use of both pidfd_send_signal and CLONE_PIDFD [2] and will use polling support and pidfd_open() too" [1] https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.9+backport%22 https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.14+backport%22 https://android-review.googlesource.com/q/topic:%22pidfd+polling+support+4.19+backport%22 [2] https://github.com/lxc/lxc/blob/aab6e3eb73c343231cdde775db938994fc6f2803/src/lxc/start.c#L1753 * tag 'pidfd-updates-v5.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: tests: add pidfd_open() tests arch: wire-up pidfd_open() pid: add pidfd_open() pidfd: add polling selftests pidfd: add polling support

git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace Pull force_sig() argument change from Eric Biederman: "A source of error over the years has been that force_sig has taken a task parameter when it is only safe to use force_sig with the current task. The force_sig function is built for delivering synchronous signals such as SIGSEGV where the userspace application caused a synchronous fault (such as a page fault) and the kernel responded with a signal. Because the name force_sig does not make this clear, and because the force_sig takes a task parameter the function force_sig has been abused for sending other kinds of signals over the years. Slowly those have been fixed when the oopses have been tracked down. This set of changes fixes the remaining abusers of force_sig and carefully rips out the task parameter from force_sig and friends making this kind of error almost impossible in the future" * 'siginfo-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace: (27 commits) signal/x86: Move tsk inside of CONFIG_MEMORY_FAILURE in do_sigbus signal: Remove the signal number and task parameters from force_sig_info signal: Factor force_sig_info_to_task out of force_sig_info signal: Generate the siginfo in force_sig signal: Move the computation of force into send_signal and correct it. signal: Properly set TRACE_SIGNAL_LOSE_INFO in __send_signal signal: Remove the task parameter from force_sig_fault signal: Use force_sig_fault_to_task for the two calls that don't deliver to current signal: Explicitly call force_sig_fault on current signal/unicore32: Remove tsk parameter from __do_user_fault signal/arm: Remove tsk parameter from __do_user_fault signal/arm: Remove tsk parameter from ptrace_break signal/nds32: Remove tsk parameter from send_sigtrap signal/riscv: Remove tsk parameter from do_trap signal/sh: Remove tsk parameter from force_sig_info_fault signal/um: Remove task parameter from send_sigtrap signal/x86: Remove task parameter from send_sigtrap signal: Remove task parameter from force_sig_mceerr signal: Remove task parameter from force_sig signal: Remove task parameter from force_sigsegv ...

2019-06-26arch/sh: Check for kprobe trap number before trying to handle a kprobe trapMichael Karcher1-1/+2
The DIE_TRAP notifier chain is run both for kprobe traps and for BUG/WARN traps. The kprobe code assumes to be only called for BREAKPOINT_INSTRUCTION, and concludes to have hit a concurrently removed kprobe if it finds anything else at the faulting locations. This includes TRAPA_BUG_OPCODE used for BUG and WARN. The consequence is that kprobe_handler returns 1. This makes kprobe_exceptions_notify return NOTIFY_STOP, and prevents handling the BUG statement. This also prevents moving $pc away from the trap instruction, so the system locks up in an endless loop Signed-off-by: Michael Karcher <[email protected]> Signed-off-by: Yoshinori Sato <[email protected]>

Convert kdump documentation to ReST and add it to the user faced manual, as the documents are mainly focused on sysadmins that would be enabling kdump. Note: the vmcoreinfo.rst has one very long title on one of its sub-sections: PG_lru|PG_private|PG_swapcache|PG_swapbacked|PG_slab|PG_hwpoision|PG_head_mask|PAGE_BUDDY_MAPCOUNT_VALUE(~PG_buddy)|PAGE_OFFLINE_MAPCOUNT_VALUE(~PG_offline) I opted to break this one, into two entries with the same content, in order to make it easier to display after being parsed in html and PDF. The conversion is actually: - add blank lines and identation in order to identify paragraphs; - fix tables markups; - add some lists markups; - mark literal blocks; - adjust title markups.

2019-05-29signal: Remove the task parameter from force_sig_faultEric W. Biederman4-5/+5
As synchronous exceptions really only make sense against the current task (otherwise how are you synchronous) remove the task parameter from from force_sig_fault to make it explicit that is what is going on. The two known exceptions that deliver a synchronous exception to a stopped ptraced task have already been changed to force_sig_fault_to_task. The callers have been changed with the following emacs regular expression (with obvious variations on the architectures that take more arguments) to avoid typos: force_sig_fault[(]\([^,]+\)[,]\([^,]+\)[,]\([^,]+\)[,]\W+current[)] -> force_sig_fault(\1,\2,\3) Signed-off-by: "Eric W.

2019-05-18treewide: prefix header search paths with $(srctree)/Masahiro Yamada1-2/+2
Currently, the Kbuild core manipulates header search paths in a crazy way [1]. To fix this mess, I want all Makefiles to add explicit $(srctree)/ to the search paths in the srctree. Some Makefiles are already written in that way, but not all. The goal of this work is to make the notation consistent, and finally get rid of the gross hacks.

2019-05-18sh: exclude vmlinux.scr from .gitignore patternMasahiro Yamada1-0/+1
arch/sh/boot/.gitignore has the pattern "vmlinux*"; this is effective not only for the current directory, but also for any sub-directories. So, from the point of .gitignore grammar, the following check-in files are also considered to be ignored: arch/sh/boot/compressed/vmlinux.scr arch/sh/boot/romimage/vmlinux.scr As the manual gitignore(5) says "Files already tracked by Git are not affected", this is not a problem as far as Git is concerned. However, Git is not the only program that parses .gitignore because .gitignore is useful to distinguish build artifacts from source files. For example, tar(1) supports the --exclude-vcs-ignore option. As of writing, this option does not work perfectly, but it intends to create a tarball excluding files specified by .gitignore. So, I believe it is better to fix this issue. Signed-off-by: Masahiro Yamada <[email protected]>

arch_add_memory, __add_pages take a want_memblock which controls whether the newly added memory should get the sysfs memblock user API (e.g. ZONE_DEVICE users do not want/need this interface). Some callers even want to control where do we allocate the memmap from by configuring altmap. Add a more generic hotplug context for arch_add_memory and __add_pages. struct mhp_restrictions contains flags which contains additional features to be enabled by the memory hotplug (MHP_MEMBLOCK_API currently) and altmap for alternative memmap allocator. This patch shouldn't introduce any functional change.

2019-05-14sh: advertise gigantic page supportAlexandre Ghiti1-0/+1
Patch series "Fix free/allocation of runtime gigantic pages", v8. This series fixes sh and sparc that did not advertise their gigantic page support and then were not able to allocate and free those pages at runtime. It renames MEMORY_ISOLATION && COMPACTION || CMA condition into the more accurate CONTIG_ALLOC, since it allows the definition of alloc_contig_range function. Finally, it then fixes the wrong definition of ARCH_HAS_GIGANTIC_PAGE config that, without MEMORY_ISOLATION && COMPACTION || CMA defined, did not allow architectures to free boottime allocated gigantic pages although unrelated. This patch (of 4): sh actually supports gigantic pages and selecting ARCH_HAS_GIGANTIC_PAGE allows it to allocate and free gigantic pages at runtime. At least sdk7786_defconfig exposes such a configuration with huge pages of 64MB, pages of 4KB and MAX_ORDER = 11: HPAGE_SHIFT (26) - PAGE_SHIFT (12) = 14 >= MAX_ORDER (11) Link: http://lkml.kernel.org/r/[email protected] Signed-off-by: Alexandre Ghiti <[email protected]> Reviewed-by: Andrew Morton <[email protected]> Cc: Aneesh Kumar K.V <[email protected]> Cc: Michael Ellerman <[email protected]> Cc: Vlastimil Babka <[email protected]> Cc: Catalin Marinas <[email protected]> Cc: Will Deacon <[email protected]> Cc: Benjamin Herrenschmidt <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Martin Schwidefsky <[email protected]> Cc: Heiko Carstens <[email protected]> Cc: Yoshinori Sato <[email protected]> Cc: Rich Felker <[email protected]> Cc: David S.

2019-05-14init: provide a generic free_initmem implementationMike Rapoport1-5/+0
Patch series "provide a generic free_initmem implementation", v2. Many architectures implement free_initmem() in exactly the same or very similar way: they wrap the call to free_initmem_default() with sometimes different 'poison' parameter. These patches switch those architectures to use a generic implementation that does free_initmem_default(POISON_FREE_INITMEM). This was inspired by Christoph's patches for free_initrd_mem [1] and I shamelessly copied changelog entries from his patches :) [1] https://lore.kernel.org/lkml/[email protected]/ This patch (of 2): For most architectures free_initmem just a wrapper for the same free_initmem_default(-1) call. Provide that as a generic implementation marked __weak.

2019-05-14mm/gup: change GUP fast to use flags rather than a write 'bool'Ira Weiny1-5/+6
To facilitate additional options to get_user_pages_fast() change the singular write parameter to be gup_flags. This patch does not change any functionality. New functionality will follow in subsequent patches. Some of the get_user_pages_fast() call sites were unchanged because they already passed FOLL_WRITE or 0 for the write parameter. NOTE: It was suggested to change the ordering of the get_user_pages_fast() arguments to ensure that callers were converted. This breaks the current GUP call site convention of having the returned pages be the final parameter. So the suggestion was rejected.
