Mostly the GCC10 yylloc failure was seen but several others have been
observed:
* wireguard script was silently failing
* several gcc10 x86 errors
* a checksum from kernel.org has changed
Now we have 3 different gcc10 yylloc patches:
gcc10-extern_YYLOC_global_declaration.patch:
Linux < 4.2
linux4.2-gcc10-extern_YYLOC_global_declaration.patch:
Linux 4.2+
linux4.17-gcc10-extern_YYLOC_global_declaration.patch:
Linux 4.17+

Subject: [PATCH] net: phy: micrel: Use strlcpy() for ethtool::get_strings
|
|
|
|
commit 55f53567afe5f0cd2fd9e006b174c08c31c466f8 upstream.
|
|
|
|
Our statistics strings are allocated at initialization without being
|
|
bound to a specific size, yet, we would copy ETH_GSTRING_LEN bytes using
|
|
memcpy() which would create out of bounds accesses, this was flagged by
|
|
KASAN. Replace this with strlcpy() to make sure we are bound the source
|
|
buffer size and we also always NUL-terminate strings.
|
|
|
|
Fixes: 2b2427d06426 ("phy: micrel: Add ethtool statistics counters")
