With object runtime debugging enabled, the rhashtable test suite will rightfully throw a warning "ODEBUG: object is on stack, but not annotated" from rhashtable_init(). This is because run_work is (correctly) being initialized via INIT_WORK(), and not annotated by INIT_WORK_ONSTACK(). Meaning, rhashtable_init() is okay as is, we just need to move ht e.g., into global scope. It never triggered anything, since test_rhashtable is rather a controlled environment and effectively runs to completion, so that stack memory is not vanishing underneath us, we shouldn't confuse any testers with it though.

The ltpc driver is rather outdated and does not get built on most platforms because it requires the ISA_DMA_API symbol. However there are some ARM platforms that have ISA_DMA_API but no virt_to_bus, and they get this build error when enabling the ltpc driver. drivers/net/appletalk/ltpc.c: In function 'handlefc': drivers/net/appletalk/ltpc.c:380:2: error: implicit declaration of function 'virt_to_bus' [-Werror=implicit-function-declaration] set_dma_addr(dma,virt_to_bus(ltdmacbuf)); ^ This adds another dependency in Kconfig to avoid that configuration.

The smc91x driver tries to support multiple platforms at compile time, but they are mutually exclusive at runtime, and not clearly defined. Trying to build for CONFIG_SA1100_ASSABET without CONFIG_ASSABET_NEPONSET results in this link error: drivers/built-in.o: In function `smc_drv_probe': :(.text+0x33310c): undefined reference to `neponset_ncr_frob' since the neponset_ncr_set function is not defined otherwise. Similarly, building for both CONFIG_SA1100_ASSABET and CONFIG_SA1100_PLEB results in a different build error: smsc/smc91x.c: In function 'smc_drv_probe': smsc/smc91x.c:2299:2: error: implicit declaration of function 'neponset_ncr_set' [-Werror=implicit-function-declaration] neponset_ncr_set(NCR_ENET_OSC_EN); ^ smsc/smc91x.c:2299:19: error: 'NCR_ENET_OSC_EN' undeclared (first use in this function) neponset_ncr_set(NCR_ENET_OSC_EN); ^ This is an attempt to fix the call site responsible for both errors, making sure we call the function exactly when the driver is actually trying to run on the assabet/neponset machine. With this patch, I no longer see randconfig build errors in this file. Signed-off-by: -

Non NAPI drivers can call skb_tstamp_tx() and then sock_queue_err_skb() from hard IRQ context. Therefore, sock_dequeue_err_skb() needs to block hard irq or corruptions or hangs can happen. Signed-off-by:

skb_gro_remcsum_init() initializes the gro_remcsum.delta member only, leading to compiler warnings about a possibly uninitialized gro_remcsum.offset member: drivers/net/vxlan.c: In function ‘vxlan_gro_receive’: drivers/net/vxlan.c:602: warning: ‘grc.offset’ may be used uninitialized in this function net/ipv4/fou.c: In function ‘gue_gro_receive’: net/ipv4/fou.c:262: warning: ‘grc.offset’ may be used uninitialized in this function While these are harmless for now: - skb_gro_remcsum_process() sets offset before changing delta, - skb_gro_remcsum_cleanup() checks if delta is non-zero before accessing offset, it's safer to let the initialization function initialize all members.

If both promisc and allmulti are set, promisc should trump allmulti and disable the MAC filter; otherwise, the interface is not really promisc. Previously, this code checked IFF_ALLMULTI prior to and without regard for IFF_PROMISC; if both were set, only multicast and direct unicast traffic would make it through the filter. Signed-off-by:

Open vSwitch allows moving internal vport to different namespace while still connected to the bridge. But when namespace deleted OVS does not detach these vports, that results in dangling pointer to netdevice which causes kernel panic as follows. This issue is fixed by detaching all ovs ports from the deleted namespace at net-exit.

phy_init_eee uses phy_find_setting(phydev->speed, phydev->duplex) to find a valid entry in the settings array for the given speed and duplex value. For full duplex 1000baseT, this will return the first matching entry, which is the entry for 1000baseKX_Full. If the phy eee does not support 1000baseKX_Full, this entry will not match, causing phy_init_eee to fail for no good reason.

The gnet_stats_copy_app() function gets called, more often than not, with its second argument a pointer to an automatic variable in the caller's stack. Therefore, to avoid copying garbage afterwards when calling gnet_stats_finish_copy(), this data is better copied to a dynamically allocated memory that gets freed after use.

Commit a7854487: md: When RAID5 is dirty, force reconstruct-write instead of read-modify-write. Causes an RCW cycle to be forced even when the array is degraded. A degraded array cannot support RCW as that requires reading all data blocks, and one may be missing. Forcing an RCW when it is not possible causes a live-lock and the code spins, repeatedly deciding to do something that cannot succeed. So change the condition to only force RCW on non-degraded arrays. Reported-by:

The value resulting from the SECCOMP_RET_DATA mask could exceed MAX_ERRNO when setting errno during a SECCOMP_RET_ERRNO filter action. This makes sure we have a reliable value being set, so that an invalid errno will not be ignored by userspace. Signed-off-by:

Call __set_current_state() instead of assigning the new state directly. These interfaces also aid CONFIG_DEBUG_ATOMIC_SLEEP environments, keeping track of who changed the state. Signed-off-by:

While reporting the (refreshed) list of modules on automatic updates we may hit the page boundary of the output console and cause a stop if pagination is enabled. However, gdb does not accept user input while running over the breakpoint handler. So we get stuck, and the user is forced to interrupt gdb. Resolve this by disabling pagination during automatic symbol updates. We restore the user's configuration once done. Signed-off-by:

Analogously to the task list, convert the module list to a generator function. It noticeably simplifies the code. Signed-off-by:

The iterator does not return any task_struct from the thread_group list because the first condition in the 'if not t or ...' will only be the first time None. Instead of keeping track of the state ourself in the next() function, we fall back using Python's generator. Signed-off-by:
