I built Linux 5.2 on both my distros last night (slackware-current and Manjaro). Lots of new settings to say "N" to :-)

So far, so good on my hardware. I'm sure there will be dire looking things in the changelogs that keep me upgrading to every point release for a while, though.

VirtualBox 6.0.8 still compiles its host modules for Linux 5.2 (I don't have any Linux guests at this time so I wouldn't know about the guest additions)

Darn, I was hoping to claim bragging rights. All is well here as well. I usually answer 'm' or 'y' unless I can see a good reason why not, which is why I have lots of modules complied that I will never use. One thing that confused me, if I can tie my memory of make oldconfig with the quick look I had with make menuconfig was the new kernel hardening - memory initialization settings. I could not find anything on this by googling, but it seemed like it might be a good idea. So I winged it and picked the least impact option that was not 'off'.

I build my kernels for performance (I honestly don't give a shit about security on my desktop systems... sue me :-) so I disable such things and the CPU mitigations. I said a more emphatic no to those newer ones, because I'd rather not use gcc plugins. Poisoning the stack after syscalls doesn't sound like a performance enhancing feature either.

I'd change my tune if it was important (for example I don't neglect security on servers)

And it's already out?

And all I need to do to get a case-insensitive directory are a mkdir and a chattr?

I'm going to have to build a 5.2 kernel (and, if necessary, a new e2fsprogs) to play Quake with.

There are a number of games (Fallout, Baldur's Gate, Alpha Centauri, Quake, etc) whose mods expect a case-insensitive filesystem even when they're running in Linux (either natively or in WINE).
Just tried.

Code:
bash-5.0# mkdir a
bash-5.0# chattr +F a
chattr: Operation not supported while setting flags on a
I created the filesystem in mid May, and I assume it's not working for me because it doesn't have the casefold feature.

How to add it?

As far as I can tell, it's by adding the "encoding" extended attribute when creating the filesystem.

http://man7.org/linux/man-pages/man8/mke2fs.8.html

I'll have to look into this more later.

And... I see this in "make menuconfig", under "File Systems":

[ ] UTF-8 normalization and casefolding support
Pretty good idea of what I need to try next. Will do it later.

Egads some of the bugs fixed in 4.4.185 look bad, especially the memory paging one (second patch from the bottom of the changelog). Worthwhile fixes for alsa, crypto, bluetooth, ipv4 too.

I have a changelog summarizer script half-written. Need to finish it so finding the important bits is easier.

I rebuilt a 5.2.0 kernel with CONFIG_UNICODE (which resulted in the entire kernel being rebuilt), and yes it worked!

Code:
bash-5.0# fallocate -l 512M test.img
bash-5.0# mkfs -t ext4 -E encoding=utf8 test.img
mke2fs 1.45.2 (27-May-2019)

Superblock backups stored on blocks:
        32768, 98304

Allocating group tables: done
Writing inode tables: done
Creating journal (4096 blocks): done
Writing superblocks and filesystem accounting information: done

bash-5.0# mkdir test
bash-5.0# mount test.img test
bash-5.0# cd test
bash-5.0# mkdir dos
bash-5.0# chattr +F dos
bash-5.0# cd dos
bash-5.0# touch a.txt
bash-5.0# touch A.txt
bash-5.0# ls
a.txt
bash-5.0# mkdir b
bash-5.0# touch b/a.txt
bash-5.0# touch b/A.txt
bash-5.0# ls b
a.txt
If you don't want to click through the reply links to see what this is about:

I created an ext4 filesystem with casefold support, mounted it, and created a directory in it called "dos". I then made that directory case-insensitive by running "chattr +F" on it.

The rest is testing that the case-insensitivity worked.

mwifiex: Fix possible buffer overflows at parsing bss descriptor

[ Upstream commit 13ec7f10b87f5fc04c4ccbd491c94c7980236a74 ]

mwifiex_update_bss_desc_with_ie() calls memcpy() unconditionally in
a couple places without checking the destination size. Since the
source is given from user-space, this may trigger a heap buffer
overflow.

Fix it by putting the length check before performing memcpy().

This fix addresses CVE-2019-3846.

Unfortunately they didn't work, the 32-bit kernel has stuck at 4.4.184 and the 64-bit at 4.4.182, so no changes.

Yes, usually I check once or twice a day and noticed it didn't work the last time around.
I really hope Dave is OK.
Does anyone know if something has happened to him or did he simply get tried of maintaining the scripts?
