I've prepared a preliminary set of patches that makes ASan work with 32-byte shadow granularity, and I would like to get some feedback on those patches as well as my general plan. Some background: I am porting ASan to the Myriad platform. I'm looking to break up that port into components that may be useful/relevant to other platforms -- the first of those pieces is the ability to use a...

...out. These parameteres may be passed from arbitrary kernel virtual memory, so they deserve strict protection to stop a bad BIOS from smashing beyond the object size. Unfortunately, the use of set_limit was badly botching this by setting the limit in terms of pages, when it really should have byte granularity.

How can I achieve granular control over the validation for different controllers? I create users from an administration controller, but I don''t want to fill in all their information fields, just have their name and email address. When they accept the invitation, I want to implement validation on the other fields. I have looked at using :on => :update, but I would have to make the

I've finished my initial set of patches to make 32-byte shadow granularity work on x86. Here is a summary of the changes from last week: - As discussed, I added a full redzone after every stack variable. - We discussed adding a -fsanitize-address-granularity=N flag, but I found the following existing flag has been sufficient for my purposes: -asan-mapping-scale N....

What I'd like to do is to copy a part of an Ogg/Vorbis file to a new file, without decoding and re-encoding (say I've got several songs in one long file, and I want to split them into separate files). Sample granularity is not required, packet granularity should do. I'm reading the Ogg documentation. I think I could write some code based on ogg_stream_packet{out,in}. Is this the way to go, or are there easier ways? Or is there perhaps already existing code for this purpose so I don't need to reinvent the...

A few folks have asked for specifics, at the spec level, on how sample granularity editing works in Vorbis. So, here's a whitepaper as the beginnings of a real document. This doc is also in CVS on branch_beta3. Note that vorbisfile is not actually tested with the beginning sample-offset spec for editing. I'll be testing/fixing any bugs in vorbisfile on that front now,...

Hi, I have a concern about the portability of offloading the new VIRTIO packed ring format to hardware. According to the PCIe rev 2.0, paragraph 2.4.2. Update Ordering and Granularity Observed by a Read Transaction" " if a host CPU writes a QWORD to host memory, a Requester reading that QWORD from host memory may observe a portion of the QWORD updated and another portion of it containing the old value." This means that after the device reads a 16byte descriptor,...

...e able to avoid running out of memory with grain of 32 than 8. The ones that run out of memory on 8 but not 32 all failed trying to allocate a large region from the heap (350M). I haven't had any tests that run out of memory for other reasons. Given that, I will check in the current selected granularity of 32. I will try grain 16 and to collect finer grained data when I have a chance.

Hi all! I''m trying to do proportional marking of real-time traffic to indicate link congestion, and for that, I wish to use the DSMARK filter to mark from, say EF to 0xcc. (an unused DSCP value) By proportional, I mean, if congestion on the egress link is, say 38%, then I shall remark 38 packets of every 100 leaving eth0. I already wrote some scripts, and I can measure the overload

Hi, I am running HTB and using the following command to get rate and pps statistics: tc -s class show dev eth0 However what I am seeing is that if I run the command over and over again, I see the sent bytes and sent packets increment however the rate and pps have the following issues: 1. The rate and pps values only seem to update after every 15 seconds 2. They do not show until about after
