[PATCH v2] mm/gup: handle NULL pages in unpin_user_pages()

by John Hubbard

The recent addition of "pofs" (pages or folios) handling to gup has a flaw: it assumes that unpin_user_pages() handles NULL pages in the pages** array. That's not the case, as I discovered when I ran on a new configuration on my test machine. Fix this by skipping NULL pages in unpin_user_pages(), just like unpin_folios() already does. Details: when booting on x86 with "numa=fake=2 movablecore=4G" on Linux 6.12, and running this: tools/testing/selftests/mm/gup_longterm ...I get the following crash: BUG: kernel NULL pointer dereference, address: 0000000000000008 RIP: 0010:sanity_check_pinned_pages+0x3a/0x2d0 ...

[PATCH v2] gpio: exar: set value when external pull-up or pull-down is present

by Sai Kumar Cholleti

Setting GPIO direction = high, sometimes results in GPIO value = 0. If a GPIO is pulled high, the following construction results in the value being 0 when the desired value is 1: $ echo "high" > /sys/class/gpio/gpio336/direction $ cat /sys/class/gpio/gpio336/value 0 Before the GPIO direction is changed from an input to an output, exar_set_value() is called with value = 1, but since the GPIO is an input when exar_set_value() is called, _regmap_update_bits() reads a 1 due to an external pull-up. regmap_set_bits() sets force_write = false, so the value (1) is not written. When the direction is then changed, the GPIO becomes an output with the value of 0 (the hardware default). regmap_write_bits() sets force_write = true, so the value is always written by exar_set_value() and an external pull-up doesn't affect the outcome of setting direction = high. The same can happen when a GPIO is pulled low, but the scenario is a little more complicated. $ echo high > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 1 $ echo in > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 0 $ echo low > /sys/class/gpio/gpio351/direction $ cat /sys/class/gpio/gpio351/value 1 Fixes: 36fb7218e878 ("gpio: exar: switch to using regmap") Signed-off-by: Sai Kumar Cholleti <skmr537(a)gmail.com> Signed-off-by: Matthew McClain <mmcclain(a)noprivs.com> Cc: <stable(a)vger.kernel.org> --- drivers/gpio/gpio-exar.c | 10 ++++++---- 1 file changed, 6 insertions(+), 4 deletions(-) diff --git a/drivers/gpio/gpio-exar.c b/drivers/gpio/gpio-exar.c index 5170fe7599cd..dfc7a9ca3e62 100644 --- a/drivers/gpio/gpio-exar.c +++ b/drivers/gpio/gpio-exar.c @@ -99,11 +99,13 @@ static void exar_set_value(struct gpio_chip *chip, unsigned int offset, struct exar_gpio_chip *exar_gpio = gpiochip_get_data(chip); unsigned int addr = exar_offset_to_lvl_addr(exar_gpio, offset); unsigned int bit = exar_offset_to_bit(exar_gpio, offset); + unsigned int bit_value = value ?

From: Nobuhiro Iwamatsu <iwamatsu(a)nigauri.org> On SoCFPGA/Sodia board, mdio bus cannot be probed, so the PHY cannot be found and the network device does not work. ``` stmmaceth ff702000.ethernet eth0: __stmmac_open: Cannot attach to PHY (error: -19) ``` To probe the mdio bus, add "snps,dwmac-mdio" as compatible string of the mdio bus.

The way to reproduce this issue: 1. Use 1600x900 to display on host 2. Mount ISO through 'Virtual media' on OpenBMC's web 3. Run script as below on host to do sha continuously #!/bin/bash while [ [1] ]; do find /media -type f -printf '"%h/%f"\n' | xargs sha256sum done 4. Open KVM on OpenBMC's web The size of macro block captured is 8x8. Therefore, we should make sure the height of src-buf is 8 aligned to fix this issue.
