Victor Kamensky authored
Currently core file of aarch32 process prstatus note has empty registers set. As result aarch32 core files create by V8 kernel are not very useful. It happens because compat_gpr_get and compat_gpr_set functions can copy registers values to/from either kbuf or ubuf. ELF core file collection function fill_thread_core_info calls compat_gpr_get with kbuf set and ubuf set to 0. But current compat_gpr_get and compat_gpr_set function handle copy to/from only ubuf case. Fix is to handle kbuf and ubuf as two separate cases in similar way as other functions like user_regset_copyout, user_regset_copyin do.

Whilst native arm64 applications don't have the 16-bit UID/GID syscalls wired up, compat tasks can still access them. The 16-bit wrappers for these syscalls use __kernel_old_uid_t and __kernel_old_gid_t, which must be 16-bit data types to maintain compatibility with the 16-bit UIDs used by compat applications. This patch defines 16-bit __kernel_old_{gid,uid}_t types for arm64 instead of using the 32-bit types provided by asm-generic.

Our compat PTRACE_POKEUSR implementation simply passes the user data to regset_copy_from_user after some simple range checking. Unfortunately, the data in question has already been copied to the kernel stack by this point, so the subsequent access_ok check fails and the ptrace request returns -EFAULT. This causes problems tracing fork() with older versions of strace. This patch briefly changes the fs to KERNEL_DS, so that the access_ok check passes even with a kernel address.

When the CMA buffer is allocated, it is too early to know whether devices will require ZONE_DMA memory. This patch limits the CMA buffer to (DMA_BIT_MASK(32) + 1) if CONFIG_ZONE_DMA is enabled. In addition, it computes the dma_to_phys(DMA_BIT_MASK(32)) before the increment (no current functional change). Signed-off-by: Catalin Marinas <catalin.marinas@arm.com>

The clean up of CALLER_ADDR*() functions required the archs to either use the default __builtin_return_address(X) (where X > 0) or override it with something the arch can use. To override it, the arch would define ftrace_return_address(x). The arm architecture requires this to be redefined but instead of defining ftrace_return_address(x) it defined ftrace_return_addr(x).

This fixes use-after-free of epi->fllink.next inside list loop macro. This loop actually releases elements in the body. The list is rcu-protected but here we cannot hold rcu_read_lock because we need to lock mutex inside. The obvious solution is to use list_for_each_entry_safe(). RCU-ness isn't essential because nobody can change this list under us, it's final fput for this file.

This reverts commit e1edf18b. This patch was a misguided attempt at fixing offb for LE ppc64 kernels on BE qemu but is just wrong ... it breaks real LE/LE setups, LE with real HW, and existing mixed endian systems that did the fight thing with the appropriate device-tree property. Bad reviewing on my part, sorry. The right fix is to either make qemu change its endian when the guest changes endian (working on that) or to use the existing foreign endian support.

Commit 0fb7a01a "random: simplify accounting code", introduced in v3.15, has a very nasty accounting problem when the entropy pool has has fewer bytes of entropy than the number of requested reserved bytes. In that case, "have_bytes - reserved" goes negative, and since size_t is unsigned, the expression: ibytes = min_t(size_t, ibytes, have_bytes - reserved); ... does not do the right thing. This is rather bad, because it defeats the catastrophic reseeding feature in the xfer_secondary_pool() path. It also can cause the "BUG: spinlock trylock failure on UP" for some kernel configurations when prandom_reseed() calls get_random_bytes() in the early init, since when the entropy count gets corrupted, credit_entropy_bits() erroneously believes that the nonblocking pool has been fully initialized (when in fact it is not), and so it calls prandom_reseed(true) recursively leading to the spinlock BUG. The logic is *not* the same it was originally, but in the cases where it matters, the behavior is the same, and the resulting code is hopefully easier to read and understand.

Commit 3fd091e7 ("[SCTP]: Remove multiple levels of msecs to jiffies conversions.") has silently changed permissions for rto_alpha and rto_beta knobs from 0644 to 0444. The purpose of this was to discourage users from tweaking rto_alpha and rto_beta knobs in production environments since they are key to correctly compute rtt/srtt. RFC4960 under section 6.3.1. RTO Calculation says regarding rto_alpha and rto_beta under rule C3 and C4: [...] C3) When a new RTT measurement R' is made, set RTTVAR <- (1 - RTO.Beta) * RTTVAR + RTO.Beta * |SRTT - R'| and SRTT <- (1 - RTO.Alpha) * SRTT + RTO.Alpha * R' Note: The value of SRTT used in the update to RTTVAR is its value before updating SRTT itself using the second assignment. After the computation, update RTO <- SRTT + 4 * RTTVAR. C4) When data is in flight and when allowed by rule C5 below, a new RTT measurement MUST be made each round trip. Furthermore, new RTT measurements SHOULD be made no more than once per round trip for a given destination transport address. There are two reasons for this recommendation: First, it appears that measuring more frequently often does not in practice yield any significant benefit [ALLMAN99]; second, if measurements are made more often, then the values of RTO.Alpha and RTO.Beta in rule C3 above should be adjusted so that SRTT and RTTVAR still adjust to changes at roughly the same rate (in terms of how many round trips it takes them to reflect new values) as they would if making only one measurement per round-trip and using RTO.Alpha and RTO.Beta as given in rule C3. However, the exact nature of these adjustments remains a research issue. [...] While it is discouraged to adjust rto_alpha and rto_beta and not further specified how to adjust them, the RFC also doesn't explicitly forbid it, but rather gives a RECOMMENDED default value (rto_alpha=3, rto_beta=2). We have a couple of users relying on the old permissions before they got changed. That said, if someone really has the urge to adjust them, we could allow it with a warning in the log.
