[PATCH] Fix NULL pointer dereference in open_memstream()
by Eugene Yudin 22 Feb '19

22 Feb '19

Hi, Current version of uClibc-ng has issue in open_memstream() function. If the cookie variable is NULL (due malloc() fail) then null pointer is dereferenced after if block. The attached patch fixes this issue. -- Best regards, Eugene

uClibc-ng 1.0.31 allowed ARM/FDPIC
by Alexey Neyman 20 Feb '19

Hi, I've noticed that uClibc-ng now allows the FDPIC ELF for ARM: one of the crosstool-NG samples that configures a toolchain for ARM with no MMU now defaults to FDPIC rather than flat format. The problem is, though, it then fails - because GCC complains that: armv6-nommu-linux-uclibcgnueabi-gcc: error: unrecognized command line option '-mfdpic'; did you mean '-fpic'? I'll fix the default in crosstool-NG, but what intrigues me is that the -mfdpic option isn't listed in GCC manual as one of the supported options for ARM (it is only listed in FRV's options). How is this configuration built? Regards, Alexey.
