2020-11-12vrf: Fix fast path output packet handling with async Netfilter rulesMartin Willi1-23/+69
VRF devices use an optimized direct path on output if a default qdisc is involved, calling Netfilter hooks directly. This path, however, does not consider Netfilter rules completing asynchronously, such as with NFQUEUE. The Netfilter okfn() is called for asynchronously accepted packets, but the VRF never passes that packet down the stack to send it out over the slave device. Using the slower redirect path for this seems not feasible, as we do not know beforehand if a Netfilter hook has asynchronously completing rules. Fix the use of asynchronously completing Netfilter rules in OUTPUT and POSTROUTING by using a special completion function that additionally calls dst_output() to pass the packet down the stack. Also, slightly adjust the use of nf_reset_ct() so that is called in the asynchronous case, too.

Check also considers prev_seq, which should be what is actually sent, not the skb data length. Avoid updating partial TAG to HW at any point of time, that's why we need to check if remaining part is smaller than TAG size, then reset TX_MAX to be TAG starting sequence number.

2020-11-11cxgb4/ch_ktls: creating skbs causes panicRohit Maheshwari3-169/+226
Creating SKB per tls record and freeing the original one causes panic. There will be race if connection reset is requested. By freeing original skb, refcnt will be decremented and that means, there is no pending record to send, and so tls_dev_del will be requested in control path while SKB of related connection is in queue. Better approach is to use same SKB to send one record (partial data) at a time. We still have to create a new SKB when partial last part of a record is requested. This fix introduces new API cxgb4_write_partial_sgl() to send partial part of skb. Present cxgb4_write_sgl can only provide feasibility to start from an offset which limits to header only and it can write sgls for the whole skb len. But this new API will help in both. It can start from any offset and can end writing in middle of the skb. v4->v5: - Removed extra changes.

2020-11-11cxgb4/ch_ktls: decrypted bit is not enoughRohit Maheshwari4-5/+8
If skb has retransmit data starting before start marker, e.g. ccs, decrypted bit won't be set for that, and if it has some data to encrypt, then it must be given to crypto ULD. So in place of decrypted, check if socket is tls offloaded. Also, unless skb has some data to encrypt, no need to give it for tls offload handling. v2->v3: - Removed ifdef.

2020-11-10lan743x: fix "BUG: invalid wait context" when setting rx modeSven Van Asbroeck2-12/+3
In the net core, the struct net_device_ops -> ndo_set_rx_mode() callback is called with the dev->addr_list_lock spinlock held. However, this driver's ndo_set_rx_mode callback eventually calls lan743x_dp_write(), which acquires a mutex. Mutex acquisition may sleep, and this is not allowed when holding a spinlock. Fix by removing the dp_lock mutex entirely. Its purpose is to prevent concurrent accesses to the data port. No concurrent accesses are possible, because the dev->addr_list_lock spinlock in the core only lets through one thread at a time.

2020-11-10lan743x: correctly handle chips with internal PHYSven Van Asbroeck1-4/+6
Commit 6f197fb63850 ("lan743x: Added fixed link and RGMII support") assumes that chips with an internal PHY will never have a devicetree entry. This is incorrect: even for these chips, a devicetree entry can be useful e.g. to pass the mac address from bootloader to chip: &pcie { status = "okay"; host@0 { reg = <0 0 0 0 0>; #address-cells = <3>; #size-cells = <2>; lan7430: ethernet@0 { /* LAN7430 with internal PHY */ compatible = "microchip,lan743x"; status = "okay"; reg = <0 0 0 0 0>; /* filled in by bootloader */ local-mac-address = [00 00 00 00 00 00]; }; }; }; If a devicetree entry is present, the driver will not attach the chip to its internal phy, and the chip will be non-operational. Fix by tweaking the phy connection algorithm: - first try to connect to a phy specified in the devicetree (could be 'real' phy, or just a 'fixed-link') - if that doesn't succeed, try to connect to an internal phy, even if the chip has a devnode Tested on a LAN7430 with internal PHY. I cannot test a device using fixed-link, as I do not have access to one.

The Medion Akoya E2228T's ACPI _LID implementation is quite broken, it has the same issues as the one from the Medion Akoya E2215T: 1. For notifications it uses an ActiveLow Edge GpioInt, rather then an ActiveBoth one, meaning that the device is only notified when the lid is closed, not when it is opened. 2. Matching with this its _LID method simply always returns 0 (closed) In order for the Linux LID code to work properly with this implementation, the lid_init_state selection needs to be set to ACPI_BUTTON_LID_INIT_OPEN, add a DMI quirk for this. While working on this I also found out that the MD60### part of the model number differs per country/batch while all of the E2215T and E2228T models have this issue, so also remove the " MD60198" part from the E2215T quirk.

Obviously, this will cause an out-of-bounds read, because we can > access a smaller vc_font.data with a larger vc_font.height. Further there was only one user ever. - Android's loadfont, busybox and console-tools only ever use OP_GET and OP_SET - fbset documentation only mentions the kernel cmdline font: option, not anything else. - systemd used OP_COPY before release 232 published in Nov 2016 Now unfortunately the crucial report seems to have gone down with gmane, and the commit message doesn't say much. But the pull request hints at OP_COPY being broken https://github.com/systemd/systemd/pull/3651 So in other words, this never worked, and the only project which foolishly every tried to use it, realized that rather quickly too. Instead of trying to fix security issues here on dead code by adding missing checks, fix the entire thing by removing the functionality. Note that systemd code using the OP_COPY function ignored the return value, so it doesn't matter what we're doing here really - just in case a lone server somewhere happens to be extremely unlucky and running an affected old version of systemd. The relevant code from font_copy_to_all_vcs() in systemd was: /* copy font from active VT, where the font was uploaded to */ cfo.op = KD_FONT_OP_COPY; cfo.height = vcs.v_active-1; /* tty1 == index 0 */ (void) ioctl(vcfd, KDFONTOP, &cfo); Note this just disables the ioctl, garbage collecting the now unused callbacks is left for -next. v2: Tetsuo found the old mail, which allowed me to find it on another archive.

RTL8125B has same or similar short packet hw padding bug as RTL8168evl.
