| * | net: hns: fix variable used when DEBUG is defined | Tom Rix | 2021-01-18 | 1 | -1/+1 |
| | | | | | | | | | | | | | | | | | | When DEBUG is defined this error occurs drivers/net/ethernet/hisilicon/hns/hns_enet.c:1505:36: error: ‘struct net_device’ has no member named ‘ae_handle’; did you mean ‘rx_handler’? assert(skb->queue_mapping < ndev->ae_handle->q_num); ^~~~~~~~~ ae_handle is an element of struct hns_nic_priv, so change ndev to priv.

| * | drivers/net/ethernet: clean up mis-targeted comments | Jesse Brandeburg | 2020-09-25 | 9 | -108/+124 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As part of the W=1 cleanups for ethernet, a million [*] driver comments had to be cleaned up to get the W=1 compilation to succeed. This change finally makes the drivers/net/ethernet tree compile with W=1 set on the command line. NOTE: The kernel uses kdoc style (see Documentation/process/kernel-doc.rst) when documenting code, not doxygen or other styles. After this patch the x86_64 build has no warnings from W=1, however scripts/kernel-doc says there are 1545 more warnings in source files, that I need to develop a script to fix in a followup patch. The errors fixed here are all kdoc of a few classes, with a few outliers: In file included from drivers/net/ethernet/qlogic/netxen/netxen_nic_hw.c:10: drivers/net/ethernet/qlogic/netxen/netxen_nic.h:1193:18: warning: ‘FW_DUMP_LEVELS’ defined but not used [-Wunused-const-variable=] 1193 | static const u32 FW_DUMP_LEVELS[] = { 0x3, 0x7, 0xf, 0x1f, 0x3f, 0x7f, 0xff }; | ^~~~~~~~~~~~~~ ... repeats 4 times... drivers/net/ethernet/sun/cassini.c:2084:24: warning: suggest braces around empty body in an ‘else’ statement [-Wempty-body] 2084 | RX_USED_ADD(page, i); drivers/net/ethernet/natsemi/ns83820.c: In function ‘phy_intr’: drivers/net/ethernet/natsemi/ns83820.c:603:6: warning: variable ‘tbisr’ set but not used [-Wunused-but-set-variable] 603 | u32 tbisr, tanar, tanlpar; | ^~~~~ drivers/net/ethernet/natsemi/ns83820.c: In function ‘ns83820_get_link_ksettings’: drivers/net/ethernet/natsemi/ns83820.c:1207:11: warning: variable ‘tanar’ set but not used [-Wunused-but-set-variable] 1207 | u32 cfg, tanar, tbicr; | ^~~~~ drivers/net/ethernet/packetengines/yellowfin.c:1063:18: warning: variable ‘yf_size’ set but not used [-Wunused-but-set-variable] 1063 | int data_size, yf_size; | ^~~~~~~ Normal kdoc fixes: warning: Function parameter or member 'x' not described in 'y' warning: Excess function parameter 'x' description in 'y' warning: Cannot understand <string> on line <NNN> - I thought it was a doc line [*] - ok it wasn't quite a million, but it felt like it.

| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Two minor conflicts: 1) net/ipv4/route.c, adding a new local variable while moving another local variable and removing it's initial assignment. 2) drivers/net/dsa/microchip/ksz9477.c, overlapping changes. One pretty prints the port mode differently, whilst another changes the driver to try and obtain the port mode from the port node rather than the switch node. Signed-off-by: David S.

| * | net: hns: Replace zero-length array with flexible-array member | Gustavo A. R. Silva | 2020-02-26 | 2 | -2/+2 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there is not enough memory and napi_alloc_skb() return NULL, the HNS driver will print error message, and than try again, if the memory is not enough for a while, huge error message and the retry operation will cause soft lockup. When napi_alloc_skb() return NULL because of no memory, we can get a warn_alloc() call trace, so this patch deletes the error message. We already use polling mode to handle irq, but the retry operation will render the polling weight inactive, this patch just return budget when the rx is not completed to avoid dead loop.

| | * | net: hns: Fix the stray netpoll locks causing deadlock in NAPI path | Salil Mehta | 2019-11-07 | 3 | -25/+1 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the problem of the spin locks, originally meant for the netpoll path of hns driver, causing deadlock in the normal NAPI poll path. The issue happened due to the presence of the stray leftover spin lock code related to the netpoll, whose support was earlier removed from the HNS[1], got activated due to enabling of NET_POLL_CONTROLLER switch. Earlier background: The netpoll handling code originally had this bug(as identified by Marc Zyngier[2]) of wrong spin lock API being used which did not disable the interrupts and hence could cause locking issues. i.e. if the lock were first acquired in context to thread like 'ip' util and this lock if ever got later acquired again in context to the interrupt context like TX/RX (Interrupts could always pre-empt the lock holding task and acquire the lock again) and hence could cause deadlock. Proposed Solution: 1. If the netpoll was enabled in the HNS driver, which is not right now, we could have simply used spin_[un]lock_irqsave() 2. But as netpoll is disabled, therefore, it is best to get rid of the existing locks and stray code for now. This should solve the problem reported by Marc.

If that qualifier is also used in the bus_find_device() prototype, it will be possible to pass the same match() callback function to both bus_find_device() and class_find_device(), which will allow some optimizations to be made in order to avoid code duplication going forward. Also with that, constify the "data" parameter as it is passed as a const to the match function. For this reason, change the prototype of bus_find_device() to match the prototype of class_find_device() and adjust its callers to use the const qualifier in accordance with the new prototype of it.

| | * | net: hns: Use NAPI_POLL_WEIGHT for hns driver | Yonglong Liu | 2019-04-04 | 1 | -5/+2 |
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the HNS driver loaded, always have an error print: "netif_napi_add() called with weight 256" This is because the kernel checks the NAPI polling weights requested by drivers and it prints an error message if a driver requests a weight bigger than 64. So use NAPI_POLL_WEIGHT to fix it. Signed-off-by: Yonglong Liu <liuyonglong@huawei.com> Signed-off-by: Peng Li <lipeng321@huawei.com> Signed-off-by: David S. Miller <davem@davemloft.net> | ||||

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is trying to fix the issue due to: [27237.844750] BUG: KASAN: use-after-free in hns_nic_net_xmit_hw+0x708/0xa18[hns_enet_drv] After hnae_queue_xmit() in hns_nic_net_xmit_hw(), can be interrupted by interruptions, and than call hns_nic_tx_poll_one() to handle the new packets, and free the skb. So, when turn back to hns_nic_net_xmit_hw(), calling skb->len will cause use-after-free. This patch update tx ring statistics in hns_nic_tx_poll_one() to fix the bug.

| * | | net: remove 'fallback' argument from dev->ndo_select_queue() | Paolo Abeni | 2019-03-20 | 1 | -3/+2 |
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the previous patch, all the callers of ndo_select_queue() provide as a 'fallback' argument netdev_pick_tx. The only exceptions are nested calls to ndo_select_queue(), which pass down the 'fallback' available in the current scope - still netdev_pick_tx. We can drop such argument and replace fallback() invocation with netdev_pick_tx(). This avoids an indirect call per xmit packet in some scenarios (TCP syn, UDP unconnected, XDP generic, pktgen) with device drivers implementing such ndo. It also clean the code a bit. Tested with ixgbe and CONFIG_FCOE=m With pktgen using queue xmit: threads vanilla patched (kpps) (kpps) 1 2334 2428 2 4166 4278 4 7895 8100 v1 -> v2: - rebased after helper's name change Signed-off-by: Paolo Abeni <pabeni@redhat.com> Signed-off-by: David S.
