patch "firmware_loader: use kernel credentials when reading firmware" added to driver-core-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled firmware_loader: use kernel credentials when reading firmware to my driver-core git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git in the driver-core-linus branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will hopefully also be merged in Linus's tree for the next -rc kernel release. If you have any questions about this process, please let me know. From 581dd69830341d299b0c097fc366097ab497d679 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Thi=C3=A9baud=20Weksteen?= <tweek(a)google.com> Date: Mon, 2 May 2022 10:49:52 +1000 Subject: firmware_loader: use kernel credentials when reading firmware MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Device drivers may decide to not load firmware when probed to avoid slowing down the boot process should the firmware filesystem not be available yet. In this case, the firmware loading request may be done when a device file associated with the driver is first accessed. The credentials of the userspace process accessing the device file may be used to validate access to the firmware files requested by the driver. Ensure that the kernel assumes the responsibility of reading the firmware. This was observed on Android for a graphic driver loading their firmware when the device file (e.g. /dev/mali0) was first opened by userspace (i.e. surfaceflinger). The security context of surfaceflinger was used to validate the access to the firmware file (e.g. /vendor/firmware/mali.bin). Previously, Android configurations were not setting up the firmware_class.path command line argument and were relying on the userspace fallback mechanism. In this case, the security context of the userspace daemon (i.e. ueventd) was consistently used to read firmware files. More Android devices are now found to set firmware_class.path which gives the kernel the opportunity to read the firmware directly (via kernel_read_file_from_path_initns). In this scenario, the current process credentials were used, even if unrelated to the loading of the firmware file.

[PATCH stable] can: isotp: remove re-binding of bound socket

by Oliver Hartkopp

[ Upstream commit 72ed3ee9fa0b461ad086403a8b5336154bd82234 ] As a carry over from the CAN_RAW socket (which allows to change the CAN interface while mantaining the filter setup) the re-binding of the CAN_ISOTP socket needs to take care about CAN ID address information and subscriptions. It turned out that this feature is so limited (e.g. the sockopts remain fix) that it finally has never been needed/used. In opposite to the stateless CAN_RAW socket the switching of the CAN ID subscriptions might additionally lead to an interrupted ongoing PDU reception. So better remove this unneeded complexity. Fixes: e057dd3fc20f ("can: add ISO 15765-2:2016 transport protocol") Link: https://lore.kernel.org/all/20220422082337.1676-1-socketcan@hartkopp.net Cc: stable(a)vger.kernel.org Signed-off-by: Oliver Hartkopp <socketcan(a)hartkopp.net> Signed-off-by: Marc Kleine-Budde <mkl(a)pengutronix.de> --- net/can/isotp.c | 22 +++++----------------- 1 file changed, 5 insertions(+), 17 deletions(-) diff --git a/net/can/isotp.c b/net/can/isotp.c index c515bbd46c67..f2f0bc7f0cb4 100644 --- a/net/can/isotp.c +++ b/net/can/isotp.c @@ -1142,24 +1142,25 @@ static int isotp_bind(struct socket *sock, struct sockaddr *uaddr, int len) if (!addr->can_ifindex) return -ENODEV; lock_sock(sk); + if (so->bound) { + err = -EINVAL; + goto out; + } + /* do not register frame reception for functional addressing */ if (so->opt.flags & CAN_ISOTP_SF_BROADCAST) do_rx_reg = 0; /* do not validate rx address for functional addressing */ if (do_rx_reg && rx_id == tx_id) { err = -EADDRNOTAVAIL; goto out; } - if (so->bound && addr->can_ifindex == so->ifindex && - rx_id == so->rxid && tx_id == so->txid) - goto out; - dev = dev_get_by_index(net, addr->can_ifindex); if (!dev) { err = -ENODEV; goto out; } @@ -1182,23 +1183,10 @@ static int isotp_bind(struct socket *sock, struct sockaddr *uaddr, int len) can_rx_register(net, dev, rx_id, SINGLE_MASK(rx_id), isotp_rcv, sk, "isotp", sk); dev_put(dev); - if (so->bound && do_rx_reg) { - /* unregister old filter */ - if (so->ifindex) { - dev = dev_get_by_index(net, so->ifindex); - if (dev) { - can_rx_unregister(net, dev, so->rxid, - SINGLE_MASK(so->rxid), - isotp_rcv, sk); - dev_put(dev); - } - } - } - /* switch to new settings */ so->ifindex = ifindex; so->rxid = rx_id; so->txid = tx_id; so->bound = 1; -- 2.30.2

[PATCH v3] f2fs: fix to do sanity check on total_data_blocks

[PATCH net v2 1/2] net: phy: micrel: Do not use kszphy_suspend/resume for KSZ8061

by Fabio Estevam

From: Fabio Estevam <festevam(a)denx.de> Since commit f1131b9c23fb ("net: phy: micrel: use kszphy_suspend()/kszphy_resume for irq aware devices") the following NULL pointer dereference is observed on a board with KSZ8061: # udhcpc -i eth0 udhcpc: started, v1.35.0 8<--- cut here --- Unable to handle kernel NULL pointer dereference at virtual address 00000008 pgd = f73cef4e [00000008] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Modules linked in: CPU: 0 PID: 196 Comm: ifconfig Not tainted 5.15.37-dirty #94 Hardware name: Freescale i.MX6 SoloX (Device Tree) PC is at kszphy_config_reset+0x10/0x114 LR is at kszphy_resume+0x24/0x64 ... The KSZ8061 phy_driver structure does not have the .probe/..driver_data fields, which means that priv is not allocated. This causes the NULL pointer dereference inside kszphy_config_reset(). Fix the problem by using the generic suspend/resume functions as before. Another alternative would be to provide the .probe and .driver_data information into the structure, but to be on the safe side, let's just restore Ethernet functionality by using the generic suspend/resume.

[PATCH] net: chelsio: cxgb4: Avoid potential negative array offset

by Kees Cook

Using min_t(int, ...) as a potential array index implies to the compiler that negative offsets should be allowed. This is not the case, though. Replace min_t() with clamp_t().
