[PATCH] kprobes: Fix random address output of blacklist file

by Thomas Richter

File /sys/kernel/debug/kprobes/blacklist displays random addresses: [root@s8360046 linux]# cat /sys/kernel/debug/kprobes/blacklist 0x0000000047149a90-0x00000000bfcb099a print_type_x8 .... This breaks 'perf probe' which uses the blacklist file to prohibit probes on certain functions by checking the address range. Fix this by printing the correct (unhashed) address. The file mode is read all but this is not an issue as the file hierarchy points out: # ls -ld /sys/ /sys/kernel/ /sys/kernel/debug/ /sys/kernel/debug/kprobes/ /sys/kernel/debug/kprobes/blacklist dr-xr-xr-x 12 root root 0 Apr 19 07:56 /sys/ drwxr-xr-x 8 root root 0 Apr 19 07:56 /sys/kernel/ drwx------ 16 root root 0 Apr 19 06:56 /sys/kernel/debug/ drwxr-xr-x 2 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/ -r--r--r-- 1 root root 0 Apr 19 06:56 /sys/kernel/debug/kprobes/blacklist Everything in and below /sys/kernel/debug is rwx to root only, no group or others have access. Background: Directory /sys/kernel/debug/kprobes is created by debugfs_create_dir() which sets the mode bits to rwxr-xr-x. Maybe change that to use the parent's directory mode bits instead?

[PATCH] x86/spectre_v2: Don't check microcode versions when running under hypervisors

by Yi Sun

From: Konrad Rzeszutek Wilk <konrad.wilk(a)oracle.com> commit 36268223c1e9981d6cfc33aff8520b3bde4b8114 upstream. As: 1) It's known that hypervisors lie about the environment anyhow (host mismatch) 2) Even if the hypervisor (Xen, KVM, VMWare, etc) provided a valid "correct" value, it all gets to be very murky when migration happens (do you provide the "new" microcode of the machine?). And in reality the cloud vendors are the ones that should make sure that the microcode that is running is correct and we should just sing lalalala and trust them.

[PATCH v2] input/touchscreen: atmel_mxt_ts: Add correct touchpad button mapping for the Caroline Chromebook.

by Vittorio Gambaletta (VittGam)

This patch adds the correct platform data information for the Caroline Chromebook, so that the mouse button does not get stuck in pressed state after the first click. The Samus button keymap and platform data definition are the correct ones for Caroline, so they have been reused here. v2: updated patch offset after 20180409 changes.

Re: Linux messages full of `random: get_random_u32 called from`

I can apply > the patch to rate limit them, but thought you may be interested in the > system I am running on, since I saw your message to Paul Menzel on lkml > (I'm not subscribed to lkml so can't simply reply to your message). Thanks for the report. It's become clear to me that we need to have the rate limiting patch backported to stable series ASAP. I'll be pushing the patch to mainline shortly. - Ted

patch "ARM: amba: Don't read past the end of sysfs "driver_override" buffer" added to char-misc-linus

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: amba: Don't read past the end of sysfs "driver_override" buffer to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-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 d2ffed5185df9d8d9ccd150e4340e3b6f96a8381 Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven <geert+renesas(a)glider.be> Date: Tue, 10 Apr 2018 15:21:45 +0200 Subject: ARM: amba: Don't read past the end of sysfs "driver_override" buffer When printing the driver_override parameter when it is 4095 and 4094 bytes long, the printing code would access invalid memory because we need count + 1 bytes for printing.
