When adding new filter to flower classifier, fl_change() inserts it to handle_idr before initializing filter extensions and assigning it a mask. Normally this ordering doesn't matter because all flower classifier ops callbacks assume rtnl lock protection. However, when filter has an action that doesn't have its kernel module loaded, rtnl lock is released before call to request_module(). During this time the filter can be accessed bu concurrent task before its initialization is completed, which can lead to a crash. Example case of NULL pointer dereference in concurrent dump: Task 1 Task 2 tc_new_tfilter() fl_change() idr_alloc_u32(fnew) fl_set_parms() tcf_exts_validate() tcf_action_init() tcf_action_init_1() rtnl_unlock() request_module() ... rtnl_lock() tc_dump_tfilter() tcf_chain_dump() fl_walk() idr_get_next_ul() tcf_node_dump() tcf_fill_node() fl_dump() mask = &f->mask->key; <- NULL ptr rtnl_lock() Extension initialization and mask assignment don't depend on fnew->handle that is allocated by idr_alloc_u32(). Move idr allocation code after action creation and mask assignment in fl_change() to prevent concurrent access to not fully initialized filter when rtnl lock is released to load action module.

A bugfix just broke compilation of appletalk when CONFIG_SYSCTL is disabled: In file included from net/appletalk/ddp.c:65: net/appletalk/ddp.c: In function 'atalk_init': include/linux/atalk.h:164:34: error: expected expression before 'do' #define atalk_register_sysctl() do { } while(0) ^~ net/appletalk/ddp.c:1934:7: note: in expansion of macro 'atalk_register_sysctl' rc = atalk_register_sysctl(); This is easier to avoid by using conventional inline functions as stubs rather than macros. The header already has inline functions for other purposes, so I'm changing over all the macros for consistency. Fixes: 6377f787 ("appletalk: Fix use-after-free in atalk_proc_exit") Signed-off-by: -

If a non local multicast packet reaches ip_route_input_rcu() while the ingress device IPv4 private data (in_dev) is NULL, we end up doing a NULL pointer dereference in IN_DEV_MFORWARD(). Since the later call to ip_route_input_mc() is going to fail if !in_dev, we can fail early in such scenario and avoid the dangerous code path. v1 -> v2: - clarified the commit message, no code changes Reported-by:

Linux supports ELF binaries for ~25 years now. a.out coredumping has bitrotten quite significantly and would need some fixing to get it into shape again but considering how even the toolchains cannot create a.out executables in its default configuration, let's deprecate a.out support and remove it a couple of releases later, instead.

We're (finally) phasing out a.out support for good. As Borislav Petkov points out, we've supported ELF binaries for about 25 years by now, and coredumping in particular has bitrotted over the years. None of the tool chains even support generating a.out binaries any more, and the plan is to deprecate a.out support entirely for the kernel. But I want to start with just removing the core dumping code, because I can still imagine that somebody actually might want to support a.out as a simpler biinary format. Particularly if you generate some random binaries on the fly, ELF is a much more complicated format (admittedly ELF also does have a lot of toolchain support, mitigating that complexity a lot and you really should have moved over in the last 25 years). So it's at least somewhat possible that somebody out there has some workflow that still involves generating and running a.out executables. In contrast, it's very unlikely that anybody depends on debugging any legacy a.out core files. But regardless, I want this phase-out to be done in two steps, so that we can resurrect a.out support (if needed) without having to resurrect the core file dumping that is almost certainly not needed. Jann Horn pointed to the <asm/a.out-core.h> file that my first trivial cut at this had missed. And Alan Cox points out that the a.out binary loader _could_ be done in user space if somebody wants to, but we might keep just the loader in the kernel if somebody really wants it, since the loader isn't that big and has no really odd special cases like the core dumping does.

The current implementation of splice() and tee() ignores O_NONBLOCK set on pipe file descriptors and checks only the SPLICE_F_NONBLOCK flag for blocking on pipe arguments. This is inconsistent since splice()-ing from/to non-pipe file descriptors does take O_NONBLOCK into consideration. Fix this by promoting O_NONBLOCK, when set on a pipe, to SPLICE_F_NONBLOCK. Some context for how the current implementation of splice() leads to inconsistent behavior. In the ongoing work[1] to add VM tracing capability to trace-cmd we stream tracing data over named FIFOs or vsockets from guests back to the host. When we receive SIGINT from user to stop tracing, we set O_NONBLOCK on the input file descriptor and set SPLICE_F_NONBLOCK for the next call to splice(). If splice() was blocked waiting on data from the input FIFO, after SIGINT splice() restarts with the same arguments (no SPLICE_F_NONBLOCK) and blocks again instead of returning -EAGAIN when no data is available. This differs from the splice() behavior when reading from a vsocket or when we're doing a traditional read()/write() loop (trace-cmd's --nosplice argument). With this patch applied we get the same behavior in all situations after setting O_NONBLOCK which also matches the behavior of doing a read()/write() loop instead of splice(). This change does have potential of breaking users who don't expect EAGAIN from splice() when SPLICE_F_NONBLOCK is not set. OTOH programs that set O_NONBLOCK and don't anticipate EAGAIN are arguably buggy[2].

Once channels were successfully opened, update tx reporter health state to healthy. This is needed for the following scenario: - SQ has an un-recovered error reported to the devlink health, resulting tx reporter state to be error. - Current channels (including this SQ) are closed - New channels are opened After that flow, the original error was "solved", and tx reporter state should be healthy. However, as it was resolved as a side effect, and not via tx reporter recover method, driver needs to inform devlink health about it. Signed-off-by:

It is possible that a reporter state will be updated due to a recover flow which is not triggered by a devlink health related operation, but as a side effect of some other operation in the system. Expose devlink health API for a direct update of a reporter status. Move devlink_health_reporter_state enum definition to devlink.h so it could be used from drivers as a parameter of devlink_health_reporter_state_update. In addition, add trace_devlink_health_reporter_state_update to provide user notification for reporter state change. Signed-off-by:
