Currently, when a socket receives something on the error queue it only wakes up the socket on select if it is in the "read" list, that is the socket has something to read. It is useful also to wake the socket if it is in the error list, which would enable software to wait on error queue packets without waking up for regular data on the socket. The main use case is for receiving timestamped transmit packets which return the timestamp to the socket via the error queue. This enables an application to select on the socket for the error queue only instead of for the regular traffic. -v2- * Added the SO_SELECT_ERR_QUEUE socket option to every architechture specific file * Modified every socket poll function that checks error queue Signed-off-by: NJacob Keller <jacob.e.keller@intel.com> Cc: Jeffrey Kirsher <jeffrey.t.kirsher@intel.com> Cc: Richard Cochran <richardcochran@gmail.com> Cc: Matthew Vick <matthew.vick@intel.com> Signed-off-by: NDavid S.

由 Vincent Bernat 提交于
While a privileged program can open a raw socket, attach some restrictive filter and drop its privileges (or send the socket to an unprivileged program through some Unix socket), the filter can still be removed or modified by the unprivileged program. This commit adds a socket option to lock the filter (SO_LOCK_FILTER) preventing any modification of a socket filter program. This is similar to OpenBSD BIOCLOCK ioctl on bpf sockets, except even root is not allowed change/drop the filter. The state of the lock can be read with getsockopt(). No error is triggered if the state is not changed. -EPERM is returned when a user tries to remove the lock or to change/remove the filter while the lock is active. The check is done directly in sk_attach_filter() and sk_detach_filter() and does not affect only setsockopt() syscall. Signed-off-by: NVincent Bernat <bernat@luffy.cx> Signed-off-by: NDavid S.

In order to promote interoperability between userspace tracers and ftrace, add a trace_clock that reports raw TSC values which will then be recorded in the ring buffer. Userspace tracers that also record TSCs are then on exactly the same time base as the kernel and events can be unambiguously interlaced. Tested: Enabled a tracepoint and the "tsc" trace_clock and saw very large timestamp values. v2: Move arch-specific bits out of generic code. v3: Rename "x86-tsc", cleanups v7: Generic arch bits in Kbuild.

The SO_ATTACH_FILTER option is set only. I propose to add the get ability by using SO_ATTACH_FILTER in getsockopt. To be less irritating to eyes the SO_GET_FILTER alias to it is declared. This ability is required by checkpoint-restore project to be able to save full state of a socket. There are two issues with getting filter back. First, kernel modifies the sock_filter->code on filter load, thus in order to return the filter element back to user we have to decode it into user-visible constants. Fortunately the modification in question is interconvertible. Second, the BPF_S_ALU_DIV_K code modifies the command argument k to speed up the run-time division by doing kernel_k = reciprocal(user_k). Bad news is that different user_k may result in same kernel_k, so we can't get the original user_k back. Good news is that we don't have to do it. What we need to is calculate a user2_k so, that reciprocal(user2_k) == reciprocal(user_k) == kernel_k i.e. if it's re-loaded back the compiled again value will be exactly the same as it was. That said, the user2_k can be calculated like this user2_k = reciprocal(kernel_k) with an exception, that if kernel_k == 0, then user2_k == 1. The optlen argument is treated like this -- when zero, kernel returns the amount of sock_fprog elements in filter, otherwise it should be large enough for the sock_fprog array. changes since v1: * Declared SO_GET_FILTER in all arch headers * Added decode of vlan-tag codes Signed-off-by: NPavel Emelyanov <xemul@parallels.com> Signed-off-by: NDavid S.

Historically, the top three bytes of personality have been used for things such as ADDR_NO_RANDOMIZE, which made sense only for specific architectures. We now however have a flag there that is general no matter the architecture (UNAME26); generally we have to be careful to preserve the personality flags across exec(). This patch tries to fix all architectures that forcefully overwrite personality flags during exec() (ppc32 and s390 have been fixed recently by commits f9783ec8 ("[S390] Do not clobber personality flags on exec") and 59e4c3a2 ("powerpc/32: Don't clobber personality flags on exec") in a similar way already).

Use the mapping of Elf_[SPE]hdr, Elf_Addr, Elf_Sym, Elf_Dyn, Elf_Rel/Rela, ELF_R_TYPE() and ELF_R_SYM() to either the 32-bit version or the 64-bit version into asm-generic/module.h for all arches bar MIPS. Also, use the generic definition mod_arch_specific where possible. To this end, I've defined three new config bools: (*) HAVE_MOD_ARCH_SPECIFIC Arches define this if they don't want to use the empty generic mod_arch_specific struct. (*) MODULES_USE_ELF_RELA Arches define this if their modules can contain RELA records. This causes the Elf_Rela mapping to be emitted and allows apply_relocate_add() to be defined by the arch rather than have the core emit an error message. (*) MODULES_USE_ELF_REL Arches define this if their modules can contain REL records. This causes the Elf_Rel mapping to be emitted and allows apply_relocate() to be defined by the arch rather than have the core emit an error message. Note that it is possible to allow both REL and RELA records: m68k and mips are two arches that do this. With this, some arch asm/module.h files can be deleted entirely and replaced with a generic-y marker in the arch Kbuild file. Additionally, I have removed the bits from m32r and score that handle the unsupported type of relocation record as that's now handled centrally.
