similar to: [PATCH] ocfs2: Access the xattr bucket only before modifying it.

When the extended attribute namespace grows to a b-tree, the leaf clusters are organized by means of 'buckets'. Each bucket is 4K in size, regardless of blocksize. Thus, a bucket may be made of more than one block. fs/ocfs2/xattr.c has a nice little abstraction to wrap this, struct ocfs2_xattr_bucket. It contains a list of buffer_heads representing these blocks, and there is even an

The patch titled Subject: fs: convert block_commit_write to return void has been added to the -mm mm-unstable branch. Its filename is fs-convert-block_commit_write-to-return-void.patch This patch will shortly appear at https://git.kernel.org/pub/scm/linux/kernel/git/akpm/25-new.git/tree/patches/fs-convert-block_commit_write-to-return-void.patch This patch will later appear in the

Hi, I am trying to control bandwidths of the connections by using TC with HTB. But I want to implement Leaky Bucket on this structure so as to have a straight flow. Due to being new in this area, could anyone help me how I could do this? Does TC support leaky bucket? Best regards, Fatih Duzova

Dear all, I''m reading codes in sch_sqf.c in kernel 2.4 of Linux. I find I messed up with the concept of slot, bucket and hash tables. Could anyone explain the data stucture of the hash tables a little to me. Thanks very much. Best, Franklin BTW: I can not understand why the number of entries of dep[SFQ_DEPTH*] should be twice:( _______________________________________________ LARTC

I got my S3 credentials defined in my production.rb, linkwise to this heroku post <https://devcenter.heroku.com/articles/paperclip-s3>. However when I''m testing it on Heroku, I get this error in my logs: "ArgumentError (missing required :bucket option)".

Hi, i have a question about throttling a token bucket. As far as i understand, if there not enough tokens to dequeue a packet from the queue, a watchdog timer will be started and the TCQ_F_THROTTLED flag will be set. But what exactly are the consequences of setting this flag. As far as i can see, it neither prevents the enqeueing nor the deqeueing of packets in both functions of the token bucket

Hello all, First I''ll state my final goal - In case someone knows an existing piece of code that does the trick: To use Linux with two network interfaces as a router and link simulator with the following features: 1. Limited bandwidth 2. Specified propagation delay which affects each packet going out of an interface 3. Limited bucket size (send buffer) for each interface. I know how to

Hi there, I just started playing around with prioritizing traffic. However I do have some questions left :P I am using the following setup: tc qdisc add dev ppp0 root handle 1: prio tc qdisc add dev ppp0 parent 1:1 handle 10: sfq tc qdisc add dev ppp0 parent 1:2 handle 20: tbf rate 61kbit latency 50ms burst 1540 tc qdisc add dev ppp0 parent 1:3 handle 30: sfq I use the mangle table of iptables

Hi, Consider below test case: 1 #include <unordered_map> 2 3 using key=const int; 4 struct Myhash { 5 Myhash() = default; 6 std::hash<int> hash_int_t; 7 inline size_t operator()(const key& x) const throw() { 8 return hash_int_t(x); 9 } 10 }; 11

I''m trying to fill a token bucket with enough tokens to burst several gigs of data. However, it doesn''t seem to get any higher than ~3.9GB: >tc qdisc add dev eth0 root tbf rate 1440kbit latency 50ms \ burst 16000000000 >tc qdisc show dev eth0 qdisc tbf 800b: rate 1440Kbit burst 3908420240b lat 2197.8s A smaller attempt of ~1.6 gigs works just fine: >tc qdisc

I am trying to create my own Token Bucket Filter. However, I have a problem with packet dropping. Scenario : I got two streams 20KB/s each. I got one bucket with rate 20KB/s I put both streams into this bucket. When buffer is full packets need to be dropped. The problem is that only every other packet needs to be dropped in this scenario. Streams are the same so queue looks like that : S1 |

Ive recently moved my files to amazon S3 storage. There is some functionality to allow an archive of files to be downloaded to a user via delayed job. So basically a project may have 10 documents in 10 different folders in the s3 bucket. What i need to do is zip the files up into one zip file and then send the user a link to download them. Im using https://github.com/qoobaa/s3 and paperclip to

Hi all, I have an average 2mbit multicast stream that once in a while bursts high (up to 20mbit/s) in short periods (about 200ms). Could anyone please help me with directions using tc for configuing leaky bucket shaping to this stream? I have a 5mbit/s ceiling. My system is running gentoo linux 2.6.14, and I have compiled in all QoS modules. Thanks. Oivind

This patch set a gap (4 bytes) between xattr entry and name/value when xattr in bucket. This gap use to seperate entry and name/value when a bucket is full. It had already been set when xattr in inode/block.

Hello, I am attempting to use the LARTC traffic control to simulate a radio link that has variable bandwidth and availability. The basic bandwidth could be as low as 500 bits/sec but will generally be about 4000 bits/sec. If the simulated radio link is unavailable (zero bandwidth) then packets should be queued until a link is re-established. i.e. Initial bandwidth is 5000bits/sec then to 0

Tristan, could you please run your xattr test against it? xs->base used to be allocated a 4K size and all the contents in the bucket are copied to the it. So in ocfs2_xattr_bucket_set_value_outside, we are safe to use xs->base + offset. Now we use ocfs2_xattr_bucket to abstract xattr bucket and xs->base is initialized to the start of the bu_bhs[0]. So xs->base + offset will overflow

in HTB use 2 bucket for manage 2 rate??? first bucket -> keep token for sending with rate second bucket -> keep ctoken for sending with ceil rate Is it true?? may be i''m misunderstand about token/bucket thoery _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc
