      uidgid: make uid_valid and gid_valid work with !CONFIG_MULTIUSER · 929aa5b2
      Josh Triplett authored
      {u,g}id_valid call {u,g}id_eq, which calls __k{u,g}id_val on both
      arguments and compares.  With !CONFIG_MULTIUSER, __k{u,g}id_val return a
      constant 0, which makes {u,g}id_valid always return false.  Change
      {u,g}id_valid to compare their argument against -1 instead.  That produces
      identical results in the normal CONFIG_MULTIUSER=y case, but with
      !CONFIG_MULTIUSER will make {u,g}id_valid constant-fold into "return
      true;" rather than "return false;".
      This fixes uses of devpts without CONFIG_MULTIUSER.

      gfp: add __GFP_NOACCOUNT · 8f4fc071
      Vladimir Davydov authored
      Not all kmem allocations should be accounted to memcg.  The following
      patch gives an example when accounting of a certain type of allocations to
      memcg can effectively result in a memory leak.  This patch adds the
      __GFP_NOACCOUNT flag which if passed to kmalloc and friends will force the
      allocation to go through the root cgroup.  It will be used by the next
      Note, since in case of kmemleak enabled each kmalloc implies yet another
      allocation from the kmemleak_object cache, we add __GFP_NOACCOUNT to
      Alternatively, we could introduce a per kmem cache flag disabling
      accounting for all allocations of a particular kind, but (a) we would not
      be able to bypass accounting for kmalloc then and (b) a kmem cache with
      this flag set could not be merged with a kmem cache without this flag,
      which would increase the number of global caches and therefore
      fragmentation even if the memory cgroup controller is not used.
      Despite its generic name, currently __GFP_NOACCOUNT disables accounting
      only for kmem allocations while user page allocations are always charged.
      To catch abusing of this flag, a warning is issued on an attempt of
      passing it to mem_cgroup_try_charge.

      pty: Fix input race when closing · 1a48632f
      Peter Hurley authored
      A read() from a pty master may mistakenly indicate EOF (errno == -EIO)
      after the pty slave has closed, even though input data remains to be read.
      For example,
             pty slave       |        input worker        |    pty master
                             |                            |
                             |                            |   n_tty_read()
      pty_write()            |                            |     input avail? no
        add data             |                            |     sleep
        schedule worker  --->|                            |     .
                             |---> flush_to_ldisc()       |     .
      pty_close()            |       fill read buffer     |     .
        wait for worker      |       wakeup reader    --->|     .
                             |       read buffer full?    |---> input avail ? yes
                             |<---   yes - exit worker    |     copy 4096 bytes to user
        TTY_OTHER_CLOSED <---|                            |<--- kick worker
                             |                            |
      		                **** New read() before worker starts ****
                             |                            |   n_tty_read()
                             |                            |     input avail? no
                             |                            |     TTY_OTHER_CLOSED? yes
                             |                            |     return -EIO
      Several conditions are required to trigger this race:
      1. the ldisc read buffer must become full so the input worker exits
      2. the read() count parameter must be >= 4096 so the ldisc read buffer
         is empty
      3. the subsequent read() occurs before the kicked worker has processed
         more input
      However, the underlying cause of the race is that data is pipelined, while
      tty state is not; ie., data already written by the pty slave end is not
      yet visible to the pty master end, but state changes by the pty slave end
      are visible to the pty master end immediately.
      Pipeline the TTY_OTHER_CLOSED state through input worker to the reader.
      1. Introduce TTY_OTHER_DONE which is set by the input worker when
         TTY_OTHER_CLOSED is set and either the input buffers are flushed or
         input processing has completed. Readers/polls are woken when
         TTY_OTHER_DONE is set.
      2. Reader/poll checks TTY_OTHER_DONE instead of TTY_OTHER_CLOSED.
      3. A new input worker is started from pty_close() after setting
         TTY_OTHER_CLOSED, which ensures the TTY_OTHER_DONE state will be
         set if the last input worker is already finished (or just about to
      Remove tty_flush_to_ldisc(); no in-tree callers.

      blk-mq: fix FUA request hang · b2387ddc
      Shaohua Li authored
      When a FUA request enters its DATA stage of flush pipeline, the
      request is added to mq requeue list, the request will then be added to
      ctx->rq_list. blk_mq_attempt_merge() might merge the request with a bio.
      Later when the request is finished the flush pipeline, the
      request->__data_len is 0. Then I only saw the bio gets endio called, the
      original request never finish.
      Adding REQ_FLUSH_SEQ into REQ_NOMERGE_FLAGS looks an easy fix.

      lib: make memzero_explicit more robust against dead store elimination · 7829fb09
      Daniel Borkmann authored
      In commit 0b053c95 ("lib: memzero_explicit: use barrier instead
      of OPTIMIZER_HIDE_VAR"), we made memzero_explicit() more robust in
      case LTO would decide to inline memzero_explicit() and eventually
      find out it could be elimiated as dead store.
      While using barrier() works well for the case of gcc, recent efforts
      from LLVMLinux people suggest to use llvm as an alternative to gcc,
      and there, Stephan found in a simple stand-alone user space example
      that llvm could nevertheless optimize and thus elimitate the memset().
      A similar issue has been observed in the referenced llvm bug report,
      which is regarded as not-a-bug.
      Based on some experiments, icc is a bit special on its own, while it
      doesn't seem to eliminate the memset(), it could do so with an own
      implementation, and then result in similar findings as with llvm.
      The fix in this patch now works for all three compilers (also tested
      with more aggressive optimization levels). Arguably, in the current
      kernel tree it's more of a theoretical issue, but imho, it's better
      to be pedantic about it.
      It's clearly visible with gcc/llvm though, with the below code: if we
      would have used barrier() only here, llvm would have omitted clearing,
      not so with barrier_data() variant:
        static inline void memzero_explicit(void *s, size_t count)
          memset(s, 0, count);
        int main(void)
          char buff[20];
          memzero_explicit(buff, sizeof(buff));
          return 0;
        $ gcc -O2 test.c
        $ gdb a.out
        (gdb) disassemble main
        Dump of assembler code for function main:

        End of assembler dump.
      As gcc, clang, but also icc defines __GNUC__, it's sufficient to define
      this in compiler-gcc.h only to be picked up. For a fallback or otherwise
      unsupported compiler, we define it as a barrier. Similarly, for ecc which
      does not support gcc inline asm.

      codel: fix maxpacket/mtu confusion · a5d28090
      Eric Dumazet authored
      Under presence of TSO/GSO/GRO packets, codel at low rates can be quite
      useless. In following example, not a single packet was ever dropped,
      while average delay in codel queue is ~100 ms !
      qdisc codel 0: parent 1:12 limit 16000p target 5.0ms interval 100.0ms
       Sent 134376498 bytes 88797 pkt (dropped 0, overlimits 0 requeues 0)
       backlog 13626b 3p requeues 0
        count 0 lastcount 0 ldelay 96.9ms drop_next 0us
        maxpacket 9084 ecn_mark 0 drop_overlimit 0
      This comes from a confusion of what should be the minimal backlog. It is
      pretty clear it is not 64KB or whatever max GSO packet ever reached the
      codel intent was to use MTU of the device.
      After the fix, we finally drop some packets, and rtt/cwnd of my single
      TCP flow are meeting our expectations.
      qdisc codel 0: parent 1:12 limit 16000p target 5.0ms interval 100.0ms

      tcp: add TCP_CC_INFO socket option · 6e9250f5
      Eric Dumazet authored
      Some Congestion Control modules can provide per flow information,
      but current way to get this information is to use netlink.
      Like TCP_INFO, let's add TCP_CC_INFO so that applications can
      issue a getsockopt() if they have a socket file descriptor,
      instead of playing complex netlink games.
      Sample usage would be :
        union tcp_cc_info info;
        socklen_t len = sizeof(info);
        if (getsockopt(fd, SOL_TCP, TCP_CC_INFO, &info, &len) == -1)

      change when a Xen guest tries to resume, it won't be calling its
      set_mode op which needs to be done on each VCPU in order to make the
      hypervisor aware that we are in oneshot mode.
      This happens because clockevents_tick_resume() (which is an intermediate
      step of resuming ticks on a processor) doesn't call clockevents_set_state()
      anymore and because during suspend clockevent devices on all VCPUs (except
      for the one doing the suspend) are left in ONESHOT state. As result, during
      resume the clockevents state machine will assume that device is already
      where it should be and doesn't need to be updated.
      To avoid this problem we should suspend ticks on all VCPUs during

      ALSA: emu10k1: Emu10k2 32 bit DMA mode · 7241ea55
      Peter Zubaj authored
      Looks like audigy emu10k2 (probably emu10k1 - sb live too) support two
      modes for DMA. Second mode is useful for 64 bit os with more then 2 GB
      of ram (fixes problems with big soundfont loading)
      1) 32MB from 2 GB address space using 8192 pages (used now as default)
      2) 16MB from 4 GB address space using 4096 pages
      Mode is set using HCFG_EXPANDED_MEM flag in HCFG register.
      Also format of emu10k2 page table is then different.

      SCSI: add 1024 max sectors black list flag · 35e9a9f9
      Mike Christie authored
      This works around a issue with qnap iscsi targets not handling large IOs
      very well.
      The target returns:
      VPD INQUIRY: Block limits page (SBC)
        Maximum compare and write length: 1 blocks
        Optimal transfer length granularity: 1 blocks
        Maximum transfer length: 4294967295 blocks
        Optimal transfer length: 4294967295 blocks
        Maximum prefetch, xdread, xdwrite transfer length: 0 blocks
        Maximum unmap LBA count: 8388607
        Maximum unmap block descriptor count: 1
        Optimal unmap granularity: 16383
        Unmap granularity alignment valid: 0
        Unmap granularity alignment: 0
        Maximum write same length: 0xffffffff blocks
        Maximum atomic transfer length: 0
        Atomic alignment: 0
        Atomic transfer length granularity: 0
      and it is *sometimes* able to handle at least one IO of size up to 8 MB. We
      have seen in traces where it will sometimes work, but other times it
      looks like it fails and it looks like it returns failures if we send
      multiple large IOs sometimes. Also it looks like it can return 2 different
      errors. It will sometimes send iscsi reject errors indicating out of
      resources or it will send invalid cdb illegal requests check conditions.
      And then when it sends iscsi rejects it does not seem to handle retries
      when there are command sequence holes, so I could not just add code to
      try and gracefully handle that error code.
      The problem is that we do not have a good contact for the company,
      so we are not able to determine under what conditions it returns
      which error and why it sometimes works.
      So, this patch just adds a new black list flag to set targets like this to
      the old max safe sectors of 1024. The max_hw_sectors changes added in 3.19
      caused this regression, so I also ccing stable.

      x86: pvclock: Really remove the sched notifier for cross-cpu migrations · 73459e2a
      Paolo Bonzini authored
      This reverts commits 0a4e6be9
      and 80f7fdb1
      The task migration notifier was originally introduced in order to support
      the pvclock vsyscall with non-synchronized TSC, but KVM only supports it
      with synchronized TSC.  Hence, on KVM the race condition is only needed
      due to a bad implementation on the host side, and even then it's so rare
      that it's mostly theoretical.
      As far as KVM is concerned it's possible to fix the host, avoiding the
      additional complexity in the vDSO and the (re)introduction of the task
      migration notifier.
      Xen, on the other hand, hasn't yet implemented vsyscall support at
      all, so we do not care about its plans for non-synchronized TSC.
