2020-07-09io_uring: export cq overflow status to userspaceXiaoguang Wang1-0/+1
For those applications which are not willing to use io_uring_enter() to reap and handle cqes, they may completely rely on liburing's io_uring_peek_cqe(), but if cq ring has overflowed, currently because io_uring_peek_cqe() is not aware of this overflow, it won't enter kernel to flush cqes, below test program can reveal this bug: static void test_cq_overflow(struct io_uring *ring) { struct io_uring_cqe *cqe; struct io_uring_sqe *sqe; int issued = 0; int ret = 0; do { sqe = io_uring_get_sqe(ring); if (!sqe) { fprintf(stderr, "get sqe failed\n"); break;; } ret = io_uring_submit(ring); if (ret <= 0) { if (ret != -EBUSY) fprintf(stderr, "sqe submit failed: %d\n", ret); break; } issued++; } while (ret > 0); assert(ret == -EBUSY); printf("issued requests: %d\n", issued); while (issued) { ret = io_uring_peek_cqe(ring, &cqe); if (ret) { if (ret != -EAGAIN) { fprintf(stderr, "peek completion failed: %s\n", strerror(ret)); break; } printf("left requets: %d\n", issued); continue; } io_uring_cqe_seen(ring, cqe); issued--; printf("left requets: %d\n", issued); } } int main(int argc, char *argv[]) { int ret; struct io_uring ring; ret = io_uring_queue_init(16, &ring, 0); if (ret) { fprintf(stderr, "ring setup failed: %d\n", ret); return 1; } test_cq_overflow(&ring); return 0; } To fix this issue, export cq overflow status to userspace by adding new IORING_SQ_CQ_OVERFLOW flag, then helper functions() in liburing, such as io_uring_peek_cqe, can be aware of this cq overflow and do flush accordingly.

2020-07-09bpf: Check correct cred for CAP_SYSLOG in bpf_dump_raw_ok()Kees Cook1-2/+2
When evaluating access control over kallsyms visibility, credentials at open() time need to be used, not the "current" creds (though in BPF's case, this has likely always been the same). Plumb access to associated file->f_cred down through bpf_dump_raw_ok() and its callers now that kallsysm_show_value() has been refactored to take struct cred.

2020-07-09kallsyms: Refactor kallsyms_show_value() to take credKees Cook2-3/+4
In order to perform future tests against the cred saved during open(), switch kallsyms_show_value() to operate on a cred, and have all current callers pass current_cred(). This makes it very obvious where callers are checking the wrong credential in their "read" contexts. These will be fixed in the coming patches. Additionally switch return value to bool, since it is always used as a direct permission check, not a 0-on-success, negative-on-error style function return.

2020-07-08Raise gcc version requirement to 4.9Linus Torvalds3-29/+3
I realize that we fairly recently raised it to 4.8, but the fact is, 4.9 is a much better minimum version to target. We have a number of workarounds for actual bugs in pre-4.9 gcc versions (including things like internal compiler errors on ARM), but we also have some syntactic workarounds for lacking features. In particular, raising the minimum to 4.9 means that we can now just assume _Generic() exists, which is likely the much better replacement for a lot of very convoluted built-time magic with conditionals on sizeof and/or __builtin_choose_expr() with same_type() etc. Using _Generic also means that you will need to have a very recent version of 'sparse', but thats easy to build yourself, and much less of a hassle than some old gcc version can be. The latest (in a long string) of reasons for minimum compiler version upgrades was commit 5435f73d5c4a ("efi/x86: Fix build with gcc 4"). Ard points out that RHEL 7 uses gcc-4.8, but the people who stay back on old RHEL versions persumably also don't build their own kernels anyway. And maybe they should cross-built or just have a little side affair with a newer compiler?

Pull io_uring fixes from Jens Axboe: "One fix in here, for a regression in 5.7 where a task is waiting in the kernel for a condition, but that condition won't become true until task_work is run. And the task_work can't be run exactly because the task is waiting in the kernel, so we'll never make any progress. One example of that is registering an eventfd and queueing io_uring work, and then the task goes and waits in eventfd read with the expectation that it'll get woken (and read an event) when the io_uring request completes.

2020-06-30task_work: teach task_work_add() to do signal_wake_up()Oleg Nesterov2-2/+7
So that the target task will exit the wait_event_interruptible-like loop and call task_work_run() asap. The patch turns "bool notify" into 0,TWA_RESUME,TWA_SIGNAL enum, the new TWA_SIGNAL flag implies signal_wake_up(). However, it needs to avoid the race with recalc_sigpending(), so the patch also adds the new JOBCTL_TASK_WORK bit included in JOBCTL_PENDING_MASK.

2020-06-26kdb: Switch to use safer dbg_io_ops over console APIsSumit Garg1-3/+2
In kgdb context, calling console handlers aren't safe due to locks used in those handlers which could in turn lead to a deadlock. Although, using oops_in_progress increases the chance to bypass locks in most console handlers but it might not be sufficient enough in case a console uses more locks (VT/TTY is good example). Currently when a driver provides both polling I/O and a console then kdb will output using the console. We can increase robustness by using the currently active polling I/O driver (which should be lockless) instead of the corresponding console. For several common cases (e.g. an embedded system with a single serial port that is used both for console output and debugger I/O) this will result in no console handler being used. In order to achieve this we need to reverse the order of preference to use dbg_io_ops (uses polling I/O mode) over console APIs. So we just store "struct console" that represents debugger I/O in dbg_io_ops and while emitting kdb messages, skip console that matches dbg_io_ops console in order to avoid duplicate messages. After this change, "is_console" param becomes redundant and hence removed.

2020-06-26mm: workingset: age nonresident information alongside anonymous pagesJohannes Weiner2-2/+3
Patch series "fix for "mm: balance LRU lists based on relative thrashing" patchset" This patchset fixes some problems of the patchset, "mm: balance LRU lists based on relative thrashing", which is now merged on the mainline. Patch "mm: workingset: let cache workingset challenge anon fix" is the result of discussion with Johannes. See following link. http://lkml.kernel.org/r/20200520232525.798933-6-hannes@cmpxchg.org And, the other two are minor things which are found when I try to rebase my patchset. This patch (of 3): After ("mm: workingset: let cache workingset challenge anon fix"), we compare refault distances to active_file + anon. But age of the non-resident information is only driven by the file LRU. As a result, we may overestimate the recency of any incoming refaults and activate them too eagerly, causing unnecessary LRU churn in certain situations. Make anon aging drive nonresident age as well to address that.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains Netfilter fixes for net, they are: 1) Unaligned atomic access in ipset, from Russell King. 2) Missing module description, from Rob Gill. 3) Patches to fix a module unload causing NULL pointer dereference in xtables, from David Wilder. For the record, I posting here his cover letter explaining the problem: A crash happened on ppc64le when running ltp network tests triggered by "rmmod iptable_mangle". See previous discussion in this thread: https://lists.openwall.net/netdev/2020/06/03/161 . In the crash I found in iptable_mangle_hook() that state->net->ipv4.iptable_mangle=NULL causing a NULL pointer dereference. net->ipv4.iptable_mangle is set to NULL in +iptable_mangle_net_exit() and called when ip_mangle modules is unloaded. A rmmod task was found running in the crash dump. A 2nd crash showed the same problem when running "rmmod iptable_filter" (net->ipv4.iptable_filter=NULL). To fix this I added .pre_exit hook in all iptable_foo.c. The pre_exit will un-register the underlying hook and exit would do the table freeing. The netns core does an unconditional +synchronize_rcu after the pre_exit hooks insuring no packets are in flight that have picked up the pointer before completing the un-register. These patches include changes for both iptables and ip6tables. We tested this fix with ltp running iptables01.sh and iptables01.sh -6 a loop for 72 hours. 4) Add a selftest for conntrack helper assignment, from Florian Westphal. ==================== Signed-off-by: David S.
