glibc: 2.23 -> 2.24
- Removed patches that were merged upstream - Removed --localdir from configureFlags as according to https://sourceware.org/bugzilla/show_bug.cgi?id=14259 it was unused before

CVE-2016-1234: glob: Do not copy d_name field of struct dirent [BZ #19779]
|
||||
|
||||
Instead, we store the data we need from the return value of
|
||||
readdir in an object of the new type struct readdir_result.
|
||||
This type is independent of the layout of struct dirent.

CVE-2016-3706: getaddrinfo: stack overflow in hostent conversion [BZ #20010]
|
||||
|
||||
When converting a struct hostent response to struct gaih_addrtuple, the
|
||||
gethosts macro (which is called from gaih_inet) used alloca, without
|
||||
malloc fallback for large responses. This commit changes this code to
|
||||
use calloc unconditionally.
|
||||
|
||||
This commit also consolidated a second hostent-to-gaih_addrtuple
|
||||
conversion loop (in gaih_inet) to use the new conversion function.

glob: Simplify the interface for the GLOB_ALTDIRFUNC callback gl_readdir
|
||||
|
||||
Previously, application code had to set up the d_namlen member if
|
||||
the target supported it, involving conditional compilation. After
|
||||
this change, glob will use the length of the string in d_name instead
|
||||
of d_namlen to determine the file name length. All glibc targets
|
||||
provide the d_type and d_ino members, and setting them as needed for
|
||||
gl_readdir is straightforward.
|
||||
|
||||
Changing the behavior with regards to d_ino is left to a future
|
||||
cleanup.
