Open Source Summit Open Source Summit is an open source technical conference in North America, gathering 2,000+ developers, operators and community leadership professionals to collaborate, share information and learn about the latest in open source technologies, including Linux, containers, cloud computing and more. At the Open Source Summit, you can expect to collaborate, share information and learn across a wide variety of topics like LinuxCon, ContainerCon, CloudOpen. read more http://events.linuxfoundation.org/events/open-source-summit-north-america/program/about SPEAKER IN OPEN SOURCE SUMMIT CONFERENCE   My last week was the best  week  than any other. Last week it was a great happened in Open Source Summit North America 2017 .   I was a speaker at the conference.  radix-tree-idr-apis-and-their-test-suite  I presented "Implementing IDR in file descriptor allocation code path". My  project deals with converting custom file descr

I have written dup3() test case. I am going to run this test case for the close_on_exec patch. Also, I have written one program (child_process.c) which will run on exec and try to open the file using fdopen(). dup3() test case is given below, 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 /* * This is dup3() functionality testcase . * The dup3() is duplicate a file descriptor to a given number,  * with flags . */ #include <s

I have written a test case of dup2() This is dup2() functionality test case. The dup2() makes newfd be the copy of oldfd, closing newfd first if necessary. This test case covers below scenarios   * Provide invalid file descriptor to dup2()   * Fill up all file descriptor table and try to duplicate a file descriptor using dup2().   * Using dup2() duplicate both file descriptor return by the pipe.   * Check inode number after passing newfd and oldfd to fstat(). inode number should be same. Upon successful execution this program will return zero value, otherwise, it will return -1. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97
