2023-11-11tracing/kprobes: Fix the order of argument descriptionsYujie Liu
The order of descriptions should be consistent with the argument list of the function, so "kretprobe" should be the second one. int __kprobe_event_gen_cmd_start(struct dynevent_cmd *cmd, bool kretprobe, const char *name, const char *loc, ...)

2023-11-10tracing: fprobe-event: Fix to check tracepoint event and returnMasami Hiramatsu (Google)
Fix to check the tracepoint event is not valid with $retval. The commit 08c9306fc2e3 ("tracing/fprobe-event: Assume fprobe is a return event by $retval") introduced automatic return probe conversion with $retval. But since tracepoint event does not support return probe, $retval is not acceptable. Without this fix, ftracetest, tprobe_syntax_errors.tc fails; [22] Tracepoint probe event parser error log check [FAIL] ---- # tail 22-tprobe_syntax_errors.tc-log.mRKroL + ftrace_errlog_check trace_fprobe t kfree ^$retval dynamic_events + printf %s t kfree + wc -c + pos=8 + printf %s t kfree ^$retval + tr -d ^ + command=t kfree $retval + echo Test command: t kfree $retval Test command: t kfree $retval + echo ---- So 't kfree $retval' should fail (tracepoint doesn't support return probe) but passed it.

2023-11-10kprobes: unify kprobes_exceptions_nofify() prototypesArnd Bergmann
Most architectures that support kprobes declare this function in their own asm/kprobes.h header and provide an override, but some are missing the prototype, which causes a warning for the __weak stub implementation: kernel/kprobes.c:1865:12: error: no previous prototype for 'kprobe_exceptions_notify' [-Werror=missing-prototypes] 1865 | int __weak kprobe_exceptions_notify(struct notifier_block *self, Move the prototype into linux/kprobes.h so it is visible to all the definitions.

2023-11-08net/sched: act_ct: Always fill offloading tuple iifidxVlad Buslov
Referenced commit doesn't always set iifidx when offloading the flow to hardware. Fix the following cases: - nf_conn_act_ct_ext_fill() is called before extension is created with nf_conn_act_ct_ext_add() in tcf_ct_act(). This can cause rule offload with unspecified iifidx when connection is offloaded after only single original-direction packet has been processed by tc data path. Always fill the new nf_conn_act_ct_ext instance after creating it in nf_conn_act_ct_ext_add(). - Offloading of unidirectional UDP NEW connections is now supported, but ct flow iifidx field is not updated when connection is promoted to bidirectional which can result reply-direction iifidx to be zero when refreshing the connection. Fill in the extension and update flow iifidx before calling flow_offload_refresh().

2023-11-08netfilter: nat: fix ipv6 nat redirect with mapped and scoped addressesFlorian Westphal
The ipv6 redirect target was derived from the ipv4 one, i.e. its identical to a 'dnat' with the first (primary) address assigned to the network interface. The code has been moved around to make it usable from nf_tables too, but its still the same as it was back when this was added in 2012. IPv6, however, has different types of addresses, if the 'wrong' address comes first the redirection does not work. In Daniels case, the addresses are: inet6 ::ffff:192 ... inet6 2a01: ... ... so the function attempts to redirect to the mapped address. Add more checks before the address is deemed correct: 1. If the packets' daddr is scoped, search for a scoped address too 2. skip tentative addresses 3. skip mapped addresses Use the first address that appears to match our needs.

2023-11-08drivers/net/ppp: use standard array-copy-functionPhilipp Stanner
In ppp_generic.c, memdup_user() is utilized to copy a userspace array. This is done without an overflow-check, which is, however, not critical because the multiplicands are an unsigned short and struct sock_filter, which is currently of size 8. Regardless, string.h now provides memdup_array_user(), a wrapper for copying userspace arrays in a standardized manner, which has the advantage of making it more obvious to the reader that an array is being copied. The wrapper additionally performs an obligatory overflow check, saving the reader the effort of analyzing the potential for overflow, and making the code a bit more robust in case of future changes to the multiplicands len * size.

2023-11-08i2c: designware: Disable TX_EMPTY irq while waiting for block length byteTam Nguyen
During SMBus block data read process, we have seen high interrupt rate because of TX_EMPTY irq status while waiting for block length byte (the first data byte after the address phase). The interrupt handler does not do anything because the internal state is kept as STATUS_WRITE_IN_PROGRESS. Hence, we should disable TX_EMPTY IRQ until I2C DesignWare receives first data byte from I2C device, then re-enable it to resume SMBus transaction. It takes 0.789 ms for host to receive data length from slave. Without the patch, i2c_dw_isr() is called 99 times by TX_EMPTY interrupt. And it is none after applying the patch.

2023-11-07r8169: respect userspace disabling IFF_MULTICASTHeiner Kallweit
So far we ignore the setting of IFF_MULTICAST. Fix this and clear bit AcceptMulticast if IFF_MULTICAST isn't set. Note: Based on the implementations I've seen it doesn't seem to be 100% clear what a driver is supposed to do if IFF_ALLMULTI is set but IFF_MULTICAST is not. This patch is based on the understanding that IFF_MULTICAST has precedence.
