1. _P_a_t_c_h__S_G_0_0_0_0_0_2_9__R_e_l_e_a_s_e__N_o_t_e
This release note describes patch SG0000029 to IRIX 5.2.
1.1 _S_u_p_p_o_r_t_e_d__H_a_r_d_w_a_r_e__P_l_a_t_f_o_r_m_s
This patch contains bug fixes for all hardware
configurations that run IRIX 5.2.
1.2 _B_u_g_s__F_i_x_e_d__b_y__P_a_t_c_h__S_G_0_0_0_0_0_2_9
This patch contains fixes for the following bugs in IRIX
5.2. Bug numbers from Silicon Graphics bug tracking system
are included for reference.
+o The _t_t_y_n_a_m_e(3) call can return two different answers
depending on inode assignment.
+o There is a bug in the _u_s_s_e_t_l_o_c_k(3P) routine in _l_i_b_c
that can cause parallel applications to livelock.
Under some conditions an application thread busy-waits
on a spinlock forever without surrendering the cpu to
allow the lock owner to release it. The bug only
affects Challenge and Onyx (bug 196622).
+o At most 524 processes can attach to the same shared
arena even if _u_s_c_o_n_f_i_g(3P) is used to set a larger
value for CONF_INITUSERS (bug 215157).
1.3 _S_u_b_s_y_s_t_e_m_s__I_n_c_l_u_d_e_d__i_n__P_a_t_c_h__S_G_0_0_0_0_0_2_9
This patch release includes these subsystems:
+o
_p_a_t_c_h_S_G_0_0_0_0_0_2_9._e_o_e_1__s_w._u_n_i_x patches to _e_o_e_1._s_w._u_n_i_x
1.4 _I_n_s_t_a_l_l_a_t_i_o_n__I_n_s_t_r_u_c_t_i_o_n_s
Because you want to install patches for only the problems
you have encountered, patch software is not installed by
default. After reading the descriptions of the bugs fixed in
this patch, determine the patches that meet your specific
needs.
Patch software is installed like any other Silicon Graphics
software product. It must be installed from the miniroot.
Follow the instructions in your _I_R_I_S _S_o_f_t_w_a_r_e _I_n_s_t_a_l_l_a_t_i_o_n
_G_u_i_d_e to bring up the miniroot form of the software
installation tools.

To remove a patch, use the _v_e_r_s_i_o_n_s _r_e_m_o_v_e command as you
would for any other software subsystem. The removal process
reinstates the original version of software unless you have
specifically removed the patch history from your system.

To keep a patch but increase your disk space, use the
_v_e_r_s_i_o_n_s _r_e_m_o_v_e_h_i_s_t command to remove the patch history.
