Created an attachment (id=63771) [details] iproute2-paretonormal-overflow.patch patch to keep paretonormal from overflowing on itself.
Taviso here is a local stack overflow.
Here is another one. maketable.c:152:Bounds error: attempt to reference memory overrunning the end of an object. maketable.c:152: Pointer value: 0x14049000, Size: 2 maketable.c:152: Object `malloc': maketable.c:152: Address in memory: 0x14047000 .. 0x14048fff maketable.c:152: Size: 8192 bytes maketable.c:152: Element size: 1 bytes maketable.c:152: Number of elements: 8192 maketable.c:152: Created at: maketable.c, line 141 maketable.c:152: Storage class: heap
latest snapshot (dated Jun 06) seems to have this issue too e-mailed iproute2 dev about the issue
just to note, this isnt a security issue because none of the netem utilites are actually installed ... they are used to generate some data tables and the tables are installed
Solar, your patch works fine here. Thanks. :)
Any date when this will be implemented into the portage tree?
i expected to hear back from the iproute2 maintainer but that hasnt happened ... ive added the patch here to the build but that still doesnt address maketable.c
Created an attachment (id=66325) [details] an ebuild for the latest iproute2 release The latest release from http://developer.osdl.org/dev/iproute2/download/ with the same Gentoo patches as iproute2-2.6.11.20050330.ebuild.
I've posted an ebuild for the latest (050816) release of iproute2. It compiles clean for me. Maybe this is what the iproute2 maintainer has been waiting for, an upstream fix.
Stale bug, reopen if you have the same problem w/ uptodate versions. Thanks.
