2021-08-26bnxt_en: Add missing DMA memory barriersMichael Chan1-0/+12
[ Upstream commit 828affc27ed43441bd1efdaf4e07e96dd43a0362 ] Each completion ring entry has a valid bit to indicate that the entry contains a valid completion event. The driver's main poll loop __bnxt_poll_work() has the proper dma_rmb() to make sure the valid bit of the next entry has been checked before proceeding further. But when we call bnxt_rx_pkt() to process the RX event, the RX completion event consists of two completion entries and only the first entry has been checked to be valid. We need the same barrier after checking the next completion entry. Add missing dma_rmb() barriers in bnxt_rx_pkt() and other similar locations. Fixes: 67a95e2022c7 ("bnxt_en: Need memory barrier when processing the completion ring.")

2021-08-26bnxt: make sure xmit_more + errors does not miss doorbellsJakub Kicinski2-13/+27
[ Upstream commit e8d8c5d80f5e9d4586c68061b62c642752289095 ] skbs are freed on error and not put on the ring. We may, however, be in a situation where we're freeing the last skb of a batch, and there is a doorbell ring pending because of xmit_more() being true earlier. Make sure we ring the door bell in such situations. Since errors are rare don't pay attention to xmit_more() and just always flush the pending frames. The busy case should be safe to be left alone because it can only happen if start_xmit races with completions and they both enable the queue. In that case the kick can't be pending. Noticed while reading the code. Fixes: 4d172f21cefe ("bnxt_en: Implement xmit_more.")

2021-08-26bnxt: don't lock the tx queue from napi pollJakub Kicinski1-22/+32
[ Upstream commit 3c603136c9f82833813af77185618de5af67676c ] We can't take the tx lock from the napi poll routine, because netpoll can poll napi at any moment, including with the tx lock already held. The tx lock is protecting against two paths - the disable path, and (as Michael points out) the NETDEV_TX_BUSY case which may occur if NAPI completions race with start_xmit and both decide to re-enable the queue. For the disable/ifdown path use synchronize_net() to make sure closing the device does not race we restarting the queues. Annotate accesses to dev_state against data races. For the NAPI cleanup vs start_xmit path - appropriate barriers are already in place in the main spot where Tx queue is stopped but we need to do the same careful dance in the TX_BUSY case.

2021-07-28bnxt_en: Check abort error state in bnxt_half_open_nic()Somnath Kotur1-0/+6
[ Upstream commit 11a39259ff79b74bc99f8b7c44075a2d6d5e7ab1 ] bnxt_half_open_nic() is called during during ethtool self test and is protected by rtnl_lock. Firmware reset can be happening at the same time. Only critical portions of the entire firmware reset sequence are protected by the rtnl_lock. It is possible that bnxt_half_open_nic() can be called when the firmware reset sequence is aborting. In that case, bnxt_half_open_nic() needs to check if the ABORT_ERR flag is set and abort if it is. The ethtool self test will fail but the NIC will be brought to a consistent IF_DOWN state. Without this patch, if bnxt_half_open_nic() were to continue in this error state, it may crash like this: bnxt_en 0000:82:00.1 enp130s0f1np1: FW reset in progress during close, FW reset will be aborted Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 ...

commit 5a3c680aa2c12c90c44af383fe6882a39875ab81 upstream. Setting the EXT_ENERGY_DET_MASK bit allows the port energy detection logic of the internal PHY to prevent the system from sleeping. Some internal PHYs will report that energy is detected when the network interface is closed which can prevent the system from going to sleep if WoL is enabled when the interface is brought down. Since the driver does not support waking the system on this logic, this commit clears the bit whenever the internal PHY is powered up and the other logic for manipulating the bit is removed since it serves no useful function.

Firmware previously only allowed promiscuous mode for VFs associated with a default VLAN. It is now possible to enable promiscuous mode for a VF having no VLAN configured provided that it is trusted. In such cases the VF will see all packets received by the PF, irrespective of destination MAC or VLAN. Note, it is necessary to query firmware at the time of bnxt_promisc_ok() instead of in bnxt_hwrm_func_qcfg() because the trusted status might be altered by the PF after the VF has been configured. This check must now also be deferred because the firmware call sleeps.

2021-04-26bnxt_en: Fix RX consumer index logic in the error path.Michael Chan1-2/+4
In bnxt_rx_pkt(), the RX buffers are expected to complete in order. If the RX consumer index indicates an out of order buffer completion, it means we are hitting a hardware bug and the driver will abort all remaining RX packets and reset the RX ring. The RX consumer index that we pass to bnxt_discard_rx() is not correct. We should be passing the current index (tmp_raw_cons) instead of the old index (raw_cons). This bug can cause us to be at the wrong index when trying to abort the next RX packet. It can crash like this: #0 [ffff9bbcdf5c39a8] machine_kexec at ffffffff9b05e007 #1 [ffff9bbcdf5c3a00] __crash_kexec at ffffffff9b111232 #2 [ffff9bbcdf5c3ad0] panic at ffffffff9b07d61e #3 [ffff9bbcdf5c3b50] oops_end at ffffffff9b030978 #4 [ffff9bbcdf5c3b78] no_context at ffffffff9b06aaf0 #5 [ffff9bbcdf5c3bd8] __bad_area_nosemaphore at ffffffff9b06ae2e #6 [ffff9bbcdf5c3c28] bad_area_nosemaphore at ffffffff9b06af24 #7 [ffff9bbcdf5c3c38] __do_page_fault at ffffffff9b06b67e #8 [ffff9bbcdf5c3cb0] do_page_fault at ffffffff9b06bb12 #9 [ffff9bbcdf5c3ce0] page_fault at ffffffff9bc015c5 [exception RIP: bnxt_rx_pkt+237] RIP: ffffffffc0259cdd RSP: ffff9bbcdf5c3d98 RFLAGS: 00010213 RAX: 000000005dd8097f RBX: ffff9ba4cb11b7e0 RCX: ffffa923cf6e9000 RDX: 0000000000000fff RSI: 0000000000000627 RDI: 0000000000001000 RBP: ffff9bbcdf5c3e60 R8: 0000000000420003 R9: 000000000000020d R10: ffffa923cf6ec138 R11: ffff9bbcdf5c3e83 R12: ffff9ba4d6f928c0 R13: ffff9ba4cac28080 R14: ffff9ba4cb11b7f0 R15: ffff9ba4d5a30000 ORIG_RAX: ffffffffffffffff CS: 0010 SS: 0018 Fixes: a1b0e4e684e9 ("bnxt_en: Improve RX consumer index validity check.")

The problem is that bnxt_show_temp() returns long but "rc" is an int and "len" is a u32. With ternary operations the type promotion is quite tricky.

2021-04-14of: net: pass the dst buffer to of_get_mac_address()Michael Walle4-22/+13
of_get_mac_address() returns a "const void*" pointer to a MAC address. Lately, support to fetch the MAC address by an NVMEM provider was added. But this will only work with platform devices. It will not work with PCI devices (e.g. of an integrated root complex) and esp. not with DSA ports. There is an of_* variant of the nvmem binding which works without devices. The returned data of a nvmem_cell_read() has to be freed after use. On the other hand the return of_get_mac_address() points to some static data without a lifetime. The trick for now, was to allocate a device resource managed buffer which is then returned. This will only work if we have an actual device. Change it, so that the caller of of_get_mac_address() has to supply a buffer where the MAC address is written to. Unfortunately, this will touch all drivers which use the of_get_mac_address(). Usually the code looks like: const char *addr; addr = of_get_mac_address(np); if (!IS_ERR(addr)) ether_addr_copy(ndev->dev_addr, addr); This can then be simply rewritten as: of_get_mac_address(np, ndev->dev_addr); Sometimes is_valid_ether_addr() is used to test the MAC address. of_get_mac_address() already makes sure, it just returns a valid MAC address. Thus we can just test its return code. But we have to be careful if there are still other sources for the MAC address before the of_get_mac_address(). In this case we have to keep the is_valid_ether_addr() call. The following coccinelle patch was used to convert common cases to the new style. Afterwards, I've manually gone over the drivers and fixed the return code variable: either used a new one or if one was already available use that. Mansour Moufid, thanks for that coccinelle patch! <spml> @a@ identifier x; expression y, z; @@ - x = of_get_mac_address(y); + x = of_get_mac_address(y, z); <... - ether_addr_copy(z, x); ...> @@ identifier a.x; @@ - if (<+... x ...+>) {} @@ identifier a.x; @@ if (<+... x ...+>) { ... } - else {} @@ identifier a.x; expression e; @@ - if (<+... x ...+>@e) - {} - else + if (!(e)) {...} @@ expression x, y, z; @@ - x = of_get_mac_address(y, z); + of_get_mac_address(y, z); ... when != x </spml> All drivers, except drivers/net/ethernet/aeroflex/greth.c, were compile-time tested.
