2023-10-18mei: update mei-pxp's component interface with timeoutsAlan Previn1-2/+4
In debugging platform or firmware related MEI-PXP connection issues, having a timeout when clients (such as i915) calling into mei-pxp's send/receive functions have proven useful as opposed to blocking forever until the kernel triggers a watchdog panic (when platform issues are experienced). Update the mei-pxp component interface send and receive functions to take in timeouts.

2023-10-12af_packet: Fix fortified memcpy() without flex array.Kuniyuki Iwashima1-5/+1
Sergei Trofimovich reported a regression [0] caused by commit a0ade8404c3b ("af_packet: Fix warning of fortified memcpy() in packet_getname()."). It introduced a flex array sll_addr_flex in struct sockaddr_ll as a union-ed member with sll_addr to work around the fortified memcpy() check. However, a userspace program uses a struct that has struct sockaddr_ll in the middle, where a flex array is illegal to exist. include/linux/if_packet.h:24:17: error: flexible array member 'sockaddr_ll::<unnamed union>::<unnamed struct>::sll_addr_flex' not at end of 'struct packet_info_t' 24 | __DECLARE_FLEX_ARRAY(unsigned char, sll_addr_flex); | ^~~~~~~~~~~~~~~~~~~~ To fix the regression, let's go back to the first attempt [1] telling memcpy() the actual size of the array.

2023-10-11cpu-hotplug: Provide prototypes for arch CPU registrationRussell King (Oracle)2-5/+2
Provide common prototypes for arch_register_cpu() and arch_unregister_cpu(). These are called by acpi_processor.c, with weak versions, so the prototype for this is already set. It is generally not necessary for function prototypes to be conditional on preprocessor macros. Some architectures (e.g. Loongarch) are missing the prototype for this, and rather than add it to Loongarch's asm/cpu.h, do the job once for everyone. Since this covers everyone, remove the now unnecessary prototypes in asm/cpu.h, and therefore remove the 'static' from one of ia64's arch_register_cpu() definitions.

2023-10-10net: macsec: indicate next pn update when offloadingRadu Pirea (NXP OSS)1-0/+1
Indicate next PN update using update_pn flag in macsec_context. Offloaded MACsec implementations does not know whether or not the MACSEC_SA_ATTR_PN attribute was passed for an SA update and assume that next PN should always updated, but this is not always true. The PN can be reset to its initial value using the following command: $ ip macsec set macsec0 tx sa 0 off #octeontx2-pf case Or, the update PN command will succeed even if the driver does not support PN updates. $ ip macsec set macsec0 tx sa 0 pn 1 on #mscc phy driver case Comparing the initial PN with the new PN value is not a solution. When the user updates the PN using its initial value the command will succeed, even if the driver does not support it. Like this: $ ip macsec add macsec0 tx sa 0 pn 1 on key 00 \ ead3664f508eb06c40ac7104cdae4ce5 $ ip macsec set macsec0 tx sa 0 pn 1 on #mlx5 case Signed-off-by: Radu Pirea (NXP OSS) <radu-nicolae.pirea@oss.nxp.com> Reviewed-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-10-06quota: Fix slow quotaoffJan Kara2-2/+4
Eric has reported that commit dabc8b207566 ("quota: fix dqput() to follow the guarantees dquot_srcu should provide") heavily increases runtime of generic/270 xfstest for ext4 in nojournal mode. The reason for this is that ext4 in nojournal mode leaves dquots dirty until the last dqput() and thus the cleanup done in quota_release_workfn() has to write them all. Due to the way quota_release_workfn() is written this results in synchronize_srcu() call for each dirty dquot which makes the dquot cleanup when turning quotas off extremely slow. To be able to avoid synchronize_srcu() for each dirty dquot we need to rework how we track dquots to be cleaned up. Instead of keeping the last dquot reference while it is on releasing_dquots list, we drop it right away and mark the dquot with new DQ_RELEASING_B bit instead. This way we can we can remove dquot from releasing_dquots list when new reference to it is acquired and thus there's no need to call synchronize_srcu() each time we drop dq_list_lock.

2023-10-05comedi: comedi_8255: Rework subdevice initialization functionsIan Abbott1-6/+7
Comedi drivers can initialize an 8255 subdevice in I/O space by calling `subdev_8255_init()`, or in memory-mapped I/O space by calling `subdev_8255_mm_init()`, or by supplying a call-back function pointer and context to either of those functions. Change it so that a new function `subdev_8255_cb_init()` shall be called instead when supplying a callback function and context, and remove the call-back function parameter from `subdev_8255_init()` and `subdev_8255_mm_init()`. Also rename `subdev_8255_init()` to `subdev_8255_io_init()`. The parameters are changing, so might as well rename it at the same time. Also rename the `regbase` member of `struct subdev_8255_private` to `context` since this holds the context for the call-back function call.

2023-10-05comedi: comedi_8254: Use a call-back function for register accessIan Abbott1-4/+18
Rework the comedi_8254 module to use a call-back function for register access. This will make it easier to isolate the parts that will depend on the `CONFIG_HAS_IOPORT` macro being defined and also allows the possibility of supplying an external callback function during initialization by a variant of the `comedi_8254_init()` and `comedi_8254_mm_init()` functions, although that has not been implemented yet. The `struct comedi_8254` members have been changed to use a pointer to a callback function and a context of type `unsigned long`. The `comedi_8254_init()` and `comedi_8254_mm_init()` functions use an internal callback function and set the context to the base address of the registers (for `comedi_8254_mm_init()` that involves converting a `void __iomem *` to `unsigned long`). A minor change to `dio200_subdev_8254_offset()` in the amplc_dio200_common module has been made due to the changes in `struct comedi_8254`.

2023-10-05mcb: remove is_added flag from mcb_device structJorge Sanjuan Garcia1-1/+0
When calling mcb_bus_add_devices(), both mcb devices and the mcb bus will attempt to attach a device to a driver because they share the same bus_type. This causes an issue when trying to cast the container of the device to mcb_device struct using to_mcb_device(), leading to a wrong cast when the mcb_bus is added. A crash occurs when freing the ida resources as the bus numbering of mcb_bus gets confused with the is_added flag on the mcb_device struct. The only reason for this cast was to keep an is_added flag on the mcb_device struct that does not seem necessary. The function device_attach() handles already bound devices and the mcb subsystem does nothing special with this is_added flag so remove it completely.

2023-10-05tcp: fix quick-ack counting to count actual ACKs of new dataNeal Cardwell1-2/+4
This commit fixes quick-ack counting so that it only considers that a quick-ack has been provided if we are sending an ACK that newly acknowledges data. The code was erroneously using the number of data segments in outgoing skbs when deciding how many quick-ack credits to remove. This logic does not make sense, and could cause poor performance in request-response workloads, like RPC traffic, where requests or responses can be multi-segment skbs. When a TCP connection decides to send N quick-acks, that is to accelerate the cwnd growth of the congestion control module controlling the remote endpoint of the TCP connection. That quick-ack decision is purely about the incoming data and outgoing ACKs. It has nothing to do with the outgoing data or the size of outgoing data. And in particular, an ACK only serves the intended purpose of allowing the remote congestion control to grow the congestion window quickly if the ACK is ACKing or SACKing new data. The fix is simple: only count packets as serving the goal of the quickack mechanism if they are ACKing/SACKing new data. We can tell whether this is the case by checking inet_csk_ack_scheduled(), since we schedule an ACK exactly when we are ACKing/SACKing new data.

2023-10-04drm/nouveau: exec: report max pushs through getparamDanilo Krummrich1-0/+10
Report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC through DRM_IOCTL_NOUVEAU_GETPARAM. While the maximum number of IBs per ring might vary between chipsets, the kernel will make sure that userspace can only push a fraction of the maximum number of IBs per ring per job, such that we avoid a situation where there's only a single job occupying the ring, which could potentially lead to the ring run dry. Using DRM_IOCTL_NOUVEAU_GETPARAM to report the maximum number of IBs that can be pushed with a single DRM_IOCTL_NOUVEAU_EXEC implies that all channels of a given device have the same ring size.

2023-10-03ipv4/fib: send notify when delete source address routesHangbin Liu1-0/+1
After deleting an interface address in fib_del_ifaddr(), the function scans the fib_info list for stray entries and calls fib_flush() and fib_table_flush(). Then the stray entries will be deleted silently and no RTM_DELROUTE notification will be sent. This lack of notification can make routing daemons, or monitor like `ip monitor route` miss the routing changes. e.g. + ip link add dummy1 type dummy + ip link add dummy2 type dummy + ip link set dummy1 up + ip link set dummy2 up + ip addr add 192.168.5.5/24 dev dummy1 + ip route add 7.7.7.0/24 dev dummy2 src 192.168.5.5 + ip -4 route 7.7.7.0/24 dev dummy2 scope link src 192.168.5.5 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5 + ip monitor route + ip addr del 192.168.5.5/24 dev dummy1 Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5 Deleted broadcast 192.168.5.255 dev dummy1 table local proto kernel scope link src 192.168.5.5 Deleted local 192.168.5.5 dev dummy1 table local proto kernel scope host src 192.168.5.5 As Ido reminded, fib_table_flush() isn't only called when an address is deleted, but also when an interface is deleted or put down. The lack of notification in these cases is deliberate. And commit 7c6bb7d2faaf ("net/ipv6: Add knob to skip DELROUTE message on device down") introduced a sysctl to make IPv6 behave like IPv4 in this regard. So we can't send the route delete notify blindly in fib_table_flush(). To fix this issue, let's add a new flag in "struct fib_info" to track the deleted prefer source address routes, and only send notify for them. After update: + ip monitor route + ip addr del 192.168.5.5/24 dev dummy1 Deleted 192.168.5.0/24 dev dummy1 proto kernel scope link src 192.168.5.5 Deleted broadcast 192.168.5.255 dev dummy1 table local proto kernel scope link src 192.168.5.5 Deleted local 192.168.5.5 dev dummy1 table local proto kernel scope host src 192.168.5.5 Deleted 7.7.7.0/24 dev dummy2 scope link src 192.168.5.5 Suggested-by: Thomas Haller <thaller@redhat.com> Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Acked-by: Nicolas Dichtel <nicolas.dichtel@6wind.com> Reviewed-by: David Ahern <dsahern@kernel.org> Link: https://lore.kernel.org/r/20230922075508.848925-1-liuhangbin@gmail.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
